First, I knew that Fish Pros in Raleigh NC would come through for me. I really wanted some kind of live plankton food for the babies as that’s what they would get in the ocean. I figured ground up TetraMin Tropical Flakes and ground up Tetra MiniKrill (freeze dried plankton) mixed with some Wardley’s Small Fry Liquid Food and distilled water would be as good as it gets, and I think it’s a pretty good mix. But I wasn’t sure I could grind the foods small enough for the pinpoint babies. Yesterday I took a ride to Fish Pros and lo, they had a bottle of DT’s Live Marine Phytoplankton – Premium Reef Blend. So this morning I mixed ground mini-krill in a 1/2 tsp of the phytoplankton and added a few drops of Small Fry in a little distilled water and put it in the tank. For other feedings, I’ll use ground up Tropical Flakes in the phytoplankton and Small Fry liquids. That should give enough of a mix of animal and plant material in their feed. The pet food link below for the Wardley’s Small Fry says that “live food” is best but for quick backup and unexpected births, the Wardley’s Small Fry is a good substitute. The DT’s phytoplankton is live.
For those truly geeky enough to want to know a bit about what’s in these foods:
DT’s Live Marine Phytoplankton: contains live Nannochloropsis oculata (yellow-green algae), Phaeodactylum tricornutum (diatoms or algae), Chlorella (green algae)
Wardley’s Small Fry: water, egg product, yeast extract, freeze-dried Calanoid Copepods (planktonic crustaceans that make up the biggest protein source in the ocean), and some vitamins and preservatives
TetraMin Tropical Flakes: fish meal, brown rice, shrimp meal, dried yeast, wheat, oat meal, fish oil, and a variety of vitamins and minerals.
Tetra MiniKrill – Freeze-dried Plankton: freeze-dried krill – Euphausia pacifica (shrimp-like invertebrates that are part of the zooplankton)
The Tropical Flakes can stay out at room temperature. Supposedly so can the Small Fry, though once I opened it, I am refrigerating it. The minikrill are in the freezer (yes, next to the loaves of bread but I don’t think I’ll mix them up), and the DT’s phytoplankton must be refrigerated. But again, I don’t think I’ll grab the phytoplankton when reaching for my husband’s bottle of blueberry juice. 🙂 So, that’s food.
The two articles for salinity in larval crabs:
Salinity Preferences in the Stage I Zoeae of Three Temperate Zone Fiddler Crabs, Genus Uca, Paul S. Capaldo, Department of Natural Sciences, Roger Williams College, Old Ferry Lane, Bristol, RI 02809; Estuaries Vol 16, No. 4, p. 784-788 December 1993
Dispersal and Recruitment of Fiddler Crab Larvae in the Delaware River Estuary, C.E. Epifanio, K.T. Little, P.M. Rowe, College of Marine Studies, University of Delaware, Lewes, Delaware 19958, Marine Ecology – Progress Series Vol. 43: 181-188, March 24, 1988
The first article mentions the three species of fiddler crabs in the study: Uca minax (red-jointed fiddler crabs, which is what I have), Uca pugnax and Uca pugilator, the latter two preferring high salinity areas. Uca minax prefers low salinity found higher up in estuaries, nearer to fresh water sources. The latter two are located in areas closer to the ocean, pugnax in salt marshes and tidal creek banks, and pugilator in the silt and silt-clay areas. The article notes that even though all three may inhibat the same salt marsh, because of their preferences for different salinities and locations, the competition for space and food between the three groups is greatly reduced.
So, today’s entry for all those who wanted geeky specifics on food and salinities. Enjoy!

Just a reminder that coming up over the next week, the next few installments on the journey of my Under the Pier novel. I had to take a break from those for taxes, actually finishing some more chapter revisions, and of course, taking care of the “grandchildren.” But stay tuned. More to come on Under the Pier.
Re the grandchildren:
What wonderful goings on! Soooo many little black dots in the nursery and they are definitely swimming around. Many are hiding out in the shadows of the live rock caves. So tiny and already they know to hide and avoid “predators.”
I am feeding them three times a day with a mixture of ground up mini-freeze dried krill, some ground up flake food, a few drops of the liquid Small Fry baby fish food, and a little distilled water mixed in. We shall see how it goes. And no, I am not grinding the mini-krill with my husband’s lovely stone mortar and pestle that he uses for grinding up herbs and spices in the kitchen!!
Regarding salinity – it’s a tricky call. While Uca minax, which are the type of fiddler crabs I have, are seen furthest up the estuary in areas of lowest salinity, there seems to be evidence that for at least the first two weeks of their larval development (zoeae) , they actually survive and do better at a higher salinity. However there is also evidence that for the next (megalopae) stage to metamorphose into crab Stage 1, this species does best with the lower salinity seen in the upper estuary environment that the adults live in. I will post more information tomorrow including the links to the two papers I found today on this subject. Long story short today though, is that zoeae of all the species of fiddler crabs, seem to need a couple weeks of “being at sea,” hence higher salinity.
I’ll also explain about the three species used in one of the studies and how their selectivity for salinity levels puts them in different spots in the estuaries and thus probably keeps them from competing with each other for resources and food.
Also to come – I dug out the small microscope I had as a kid and will pick up some microscope slides. So to follow, descriptions of babies, under the glass.
A couple of other notes – courtesy again of my engineer husband. He noted a bunch of white things all over the gravel and wondered if the babies had already molted. Maybe they have but these white dots were too big and irregular in size for baby shells. I believe it’s salt crystals that didn’t dissolve in the water before I added it. I added more water to bring the salinity up closer to a marine environment. I started at 1.010 (brackish) when they were born and over the course of yesterday raised the salinity first to 1.012, then by last night 1.015. Today I’ll finish raising it to 1.020. Then in two weeks I’ll bring it back down to 1.010-1.012, the optimal range for Uca minax adults.
Sand. Again, my husband was watching the babies swim – it is amazing to see these tiny things whiz around the tank – but he shined a light to see if they would follow the beam. The article I posted in yesterday’s gift mentioned that the babies will go to the light. My husband didn’t see evidence of that, but what he noted was that many little babies had worked their way down between the gravel bits, all the way down to the bottom of the tank. Unless they figure out how to get back up to the water, they’ve had it. Now let’s face it. Their parents had a brain the size of a pinpoint. How large a brain do you thing babies the size of a pinpoint have? So the odds of them getting back to the surface are not good. I said “evolution at work. Anybody who tunnels down in the gravel probably won’t live to reproduce. ” My husband noted that gravel is less than optimal for this (engineers talk like this by the way, things are optimal, less than optimal, sub-optimal 🙂 ).
The real important point though was his next comment: “The NEXT time we do this, we should use sand.” There you have it folks. My husband has fallen in love with the fiddler crabs. In all truth, he has. He watches them, thinks about how to make their lives better, anticipates the babies getting ground up in the water filter…..those babies are lucky to have him!!!
Anyway, stay tuned for the links on those two articles about optimal (yes, OPTIMAL) salinity levels for fiddler crab larvae.

I came out of the gym and my cell phone went off – the vibrating beep to indicate a text message. It apparently came earlier, but given the facility is blocked I only just received it. My husband sent it – a few simple words: We’re grandparents!” I understood immediately – our pregnant fiddler crab, Scarlett O’Hara delivered her thousands of babies.
When I left this morning, she was wandering around, not really interested in eating. Just walking around. Ed noted the same thing before he went upstairs to do some work. When he came down, he said she was just sitting there eating a shrimp pellet … and she was skinny. He did a double-take and noticed the babies were gone from her abdomen, and all these little teeny really teeny black dots, floating around the tank!!!
As soon as I got the text, I raced to PetsMart to pick up the liquid baby fish food called “Small Fry” and raced home. Did you ever notice how many asleep drivers there are on the highway when you’re trying to get home fast?
I quickly got Scarlett out of the nursery tank as my husband reminded me, because at this point, Scarlett’s maternal instincts are probably done. In fact she may view them as floating “cheeseburgers” and start munching. So I moved her back into the main tank. It was like she never left. Not even a second to re-adjust for her. She just walked over to the live rock and started picking off algae and eating. Kind of like “Ahhhh – good to be home.” I don’t think Admiral Byrd has noticed her return yet. Not sure about Melanie Hamilton. She’s been in seclusion since Scarlett O’Hara left the main tank, probably hiding out from Admiral Byrd who has been waving his claw non-stop these days. I expect Melanie may be relieved to have Scarlett back.
Anyway, just had to let you all know she has successfully birthed. I will keep you posted on what happens from here. We’ll see how many, if any, of the babies survive!!! 🙂

The breeding of Red Clayed Mangrove Crabs. This gentleman succeeded in raising crabs from egg release from the female, right up to adult crabs. For information and pictures of this process, click here.
One thing of note – this gentleman said his female brooded her eggs three weeks before releasing them. We are just about at week #2 here with Scarlett O’Hara. So we shall see how long this takes. I may need to change the “baby food.” I have frozen freeze-dried mini-krill and some flake food. I figured I could grind up the krill into a power, and the flake food would dissolve and float, making both “accessible” to the tiny newborn crabs. He used a liquid “small fry” food, which I saw at Petsmart. I may try that.

Again I will note, it is my husband who thought of something crucial. I’d finally gotten the new tank so the water is clear, the nitrites aren’t too high, Scarlett O’Hara is calm and exploring the tank. I got the main tank’s water changed, so it too is in great shape. Feeling satisfied with the world, I commented that now all we need to do is wait for the birth.
My husband turned and said: “I’ve been meaning to ask you something that bothered me. You have the water filter running in the nursery tank. When the microscopic babies are born, won’t they all get sucked into the filter material?”
“OH MY GOD.” The man is right. We’ll come down some morning and Scarlett will have delivered and there’ll be no babies in the tank – just this primal cry of the thousands emitting from the cloth and charcoal filter material – the crab baby equivalent of “Oh the humanity!!”
I first thought maybe I could just pull out the filter material and just leave the water pump running, but again, my engineer husband said, “Well that will be okay I guess while they’re microscopic. But what happens when they start to grow and get a little bigger? They’ll get sucked through the pump and won’t that grind them all up?”
“OH MY GOD again.” You know, for a person who started this whole thing out with “So, we’ve spent $4 on fiddler crabs and a $100 on support gear,” and laughed at the endeavor, he is the one the babies should thank if they make it because he is the one paying such close attention to their every need. When I hedged about spending yet another $30 on a tank heater, he was like, “But won’t they need heat?”
In any event, I ran to Petsmart to buy a tank bubbler. There’s all kinds – wands, rocks, bars, then there’s pumps – all kinds of those, not to mention you have to buy the right pump to handle the volume of your tank and the right sized wand to stretch across your tank, then there’s the check valve you have to install if the pump is going to be below the aquarium instead of above it – keeps the water from backflowing into the pump in case of power loss….you get the picture. I finally settled on a pump for aquariums up to 20 gallons instead of 10. Wanted something with more power to push air in there. And I selected a wand to extend across the back of the tank to create a curtain of bubbles. I thought that might circulate the oxgen better than a bubble rock. It won’t filter the water, but hopefully the huge live rock and the bacteria I’ve already seeded the tank with from the old filter backing, will be enough to jump-start the nitrogen cycle without the filter running. The bubbler will give them fresh air. So, keep your fingers crossed.
At least Scarlett O’Hara seems to like it. She climbs up on the wand and sits there with bubbles flowing up around her. I hope she thinks it’s “surf” and releases the babies soon. My husband wonders if she is scurrying around the tank so much because it’s getting close and she’s frantically trying to find that right spot to let them go and be carried out “into the open ocean.” Sigh.
Truly, those fiddler babies owe him a lot. He is the true fiddler dad. Admiral Byrd may be oblivious and not care, but my husband surely does. It’s that whole “Caring is Catchy,” thing.

A time out, today, from both my writing journey posts and my fiddler crab posts. No new info on the latter yet, by the way. It’s like pregnant women past their due date – you just wait and don’t ask if the contractions have started yet.
Today is a special day. It is our twentieth wedding anniversary. It is a milestone, and worth taking time out to honor. The years have gone quickly, sprinkled with child-raising, dogs, sick parents, near-death experiences, heart-ache, joy, aging. A good mix for life I’d say. As I’ve noted, we are both geeks in our own ways, and as such, we understand each other. I just wanted to take a moment today to honor my best friend, and I figured he would enjoy and understand the movie reference below. He and I speak in movie references – lines from movies that capture the emotion of a moment for us. Over the years we have accumulated a collection of lines from hundreds of movies. They have become a kind of coded communication between us.
This particular movie is called 84 Charing Cross Road. Anne Bancroft stars. Her husband, Mel Brooks, purchased the rights to produce it – his gift of love to her, knowing how much she loved the story.
It’s the true story of a New York City writer, Helene Hanff – a person kind of like me – no bullsh–, doesn’t mince words, very “unglamorous.” She has a sharp, but kind sense of humor and a great heart. Helene LOVED English literature, but in late 1940s New York City where the movie begins, she could not find any English literature books except at the library. Then she discovered Marks & Co. and began a decades-long correspondence with them. The story is told through her letters. From the opening of the movie:
“October 5, 1949, to Marks and Co., 84 Charing Cross Road, London, WC2, England. Gentlemen, Your ad in the Saturday Review of Literature says that you specialize in out-of-print books. The phrase “antiquarian bookseller” scares me somewhat as I equate antique with expensive. I am a poor writer with an antiquarian taste in books and all the things I want are impossible to get over here except in very expensive rare editions. I enclose a list of my most pressing problems. If you have any clean second-hand copies of any of the books on the list for no more than $5 each, would you consider this a purchase order and send them to me?”
Thus begins her relationship with the very proper bookseller at Marks & Co., “FPD.” FPD, over letters and time becomes Frank Doel, then simply, “Frank.” It’s a love story, but not the usual kind. They live an ocean apart, have different lives, and he is married with daughters. Happily married. So no, there are no hot sex scenes, the crutch of most modern movies. Yet it is a love story, anyway, because true love at its deepest is about caring, generosity, and the connection of souls. It is not limited by the relationship but can be felt for spouses, friends, relatives, neighbors. Their friendship enlarges their lives, expanding to include his wife, neighbors, daughters, other workers at the bookshop, her friends. Their love is about adding something to each of their lives, not taking things away or destroying things. It is about understanding each other, and that is the quality of love that sustains it, whether in marriage or friendship, well into old age. And frankly, a marriage that lasts well into old age is as much about friendship, as anything else.
Throughout the movie, she revels in the old books she buys, books better for having been owned by someone else first. Again, it is a love of connection to others, even those she never met. She says: “I love inscriptions on fly-leafs and notes in margins. I like the camaraderie-sense of turning pages someone else turned and reading passages someone long gone has called my attention to.” She can’t get enough of the books. Frank finds them for her.
By the end of the movie, he is “Frankie” to her, and she tells him, “You’re the only soul alive who understands me.” It’s a sentiment that reflects a bond where you are known deeply, valued, and most importantly, accepted. Your truth is safe in the hands of another. Whether two people are the same or very different matters not if there is acceptance. When someone knows our deepest places, our vulnerabilities, and accepts us, they give us the best of gifts. The wish to be understood and accepted is one of the bonds that links us all. These are things I have felt for and from my husband.
At one point a friend of Helene’s made it to England and visited the book store. She wrote Helene with a description:
“It’s the loveliest old shop straight out of Dickens. You would go absolutely out of your mind over it….It’s dim inside. You can smell the shop before you see it. It’s a lovely smell. I can’t articulate it easily but it combines must and dust and age and walls of wood and floors of wood…The shelves go on forever. They go up to the ceiling and they’re very old and kind of gray, like old oak that absorbed so much dust over the years they no longer are their true color.”
Such a visceral, sensual description. It was a description both my husband and I fell in love with immediately when we heard it. It is a place we hope yet, to be.
At one point in the movie Helene writes to Frank:
“I require a book of love poems with Spring coming on. No Keats or Shelley. Send me poets who can make love without slobbering. Wyatt or Johnson or somebody. Use your own judgment. Just a nice book, preferably small enough to stick in a slacks pocket and take to Central Park.”
Late in the movie, Frank is shown, reflecting on her as a Yeats love poem runs through his mind. The moment, and the poem, are my gifts to my husband, my best friend. Thank you for these last 20 years. They’ve gone so fast. I’d like 20 times 20 more, and if time allows, I’d like yet to walk into 84 Charing Cross Road with you.
So to “Eddie,” all my love, and to you and all romantics out there, a poet who can make love without slobbering:
He Wishes for the Cloths of Heaven
Had I the heavens’ embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths,
Of night and light and the half light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet;
Tread softly because you tread on my dreams.
W.B. Yeats (1865-1939). The Wind Among the Reeds. 1899.

February 25, 2008
Just a quick note this morning as I’m on the run. The next installment of my author journey is partially written. Those take me a bit more time. Pondering, reflecting, remembering. Lots to sift through. So those will resume this week.
For now, just to update – Scarlett O’Hara is still alive in the new tank – the “nursery.” Frankly, I was worried. I’d have felt better if I’d set that tank up last week and it had a week to run and settle out. I just hadn’t come to the point of “embracing” trying to raise larval crabs and when I did finally decide this weekend to try, it seemed like birth was imminent. Kind of a go/no-go response needed to be made ASAP.
Last night she just wouldn’t settle down in the new tank. Kept running back and forth, kept trying to climb the sides of the tank. Was there something wrong with the water that was hurting her? All the parameters looked great, in fact the water in the new tank was better than the original – that one’s overdue for a water exchange and the nitrites and nitrates in that tank are rising. So this one is actually healthier. However, certainly there’s other parameters I can’t measure. So my worry was that I’d put her in something I thought was better for her, but maybe I was killing her and couldn’t tell?
I wondered if she was just disoriented and couldn’t find a place to climb out of the water to get air. I noticed air bubbles escaping from her mouth at one point and was afraid she would “drown.” She has this lovely live rock with all kinds of crevices she could hide in, better than her old live rock, AND it’s much bigger so she can climb on top of it, but I thought that maybe in her stress she couldn’t find it. So I scooped extra gravel out of the original tank and put it in the new one and built her two gravel hills so she could walk up the hill and be partly out of water. She found them, but that didn’t seem to be the problem. She just kept running back and forth and climbing the walls.
My husband wondered if she simply couldn’t understand why the sides of this tank were so clean and where was all the microscopic algae she likes to eat? The other tank, though the glass sides look clear, apparently have microscopic algae on them because the crabs are always “picking stuff off” the sides and eating it.
Or maybe she was just so stressed out, she couldn’t relax and would kill herself with exhaustion?
I also noted last night that the formerly clear water in the new tank was now cloudy. I was convinced something awful was taking hold and maybe the live rock had something bad in it. If so, you would expect the nitrites to be rising. I repeated all parameters last night and the water looked good.
So by this point, who is more stressed? Her or me?
My husband said little, just said “It’ll be what it’ll be. You’ve done all you can.” I told him it’s not easy being “God.” He patted my back and said “At least not a God who cares.”
Anyway, I struggled with “should I just bag this whole thing and put her back in the original tank?” I decided not to add any more stress to her by moving her back. One of those – just let it go and see what happens, moments.
This morning the tank looks less cloudy. My husband said he came down and she was sitting quietly in the water, “tending” to her egg mass – ie – giving it pushes and pokes, as if turning them. When I came down, she had found her way to the top of the live rock and was just sitting there on top of her world, soaking up heat from the lights and appearing totally relaxed. (Or is she dead? Should I poke her? 🙂 Just kidding).
All joking aside about my being so worried, I guess I felt guilty. As I said to my husband – Did I put her at risk of dying because I so wanted to try and raise the babies? Did my ego cause harm in this and should I have just left it all alone?
The ethical questions are never clear or easily answered. It’s like being a parent. You try your best, knowing that even when you do, you don’t know if you’ve made the right choices. And in your less than perfect moments, and we all have them, you wonder, will they be okay? Why does God entrust such a big job to mere mortals?
I think Lee Woodruff’s final comments in her book, In An Instant, apply here, at least for being parents, maybe not for being God to fiddler crabs. She worried about how her kids were affected by all the turmoil and intensity when her reporter husband, Bob, was in the hospital with a head injury. She had to be away for long periods to be with him. Things were in an upheaval even though family and friends were looking after things. I so loved her observations, because they are the truth. In thanking her kids she added:
“May you always remember that there are no perfect parents, just mothers and fathers doing the very best they can. And there are no perfect spouses either, just those who love each other enough to stand by “for better or worse.” Don’t be fooled: that kind of endurance is, perhaps, the greatest expression of love.”
I think she could only come to that lesson because of the messiness of life. I think it’s the messy low moments that teach us the most about being human, and about understanding the “human moments” in others. Those times teach us about being compassionate to ourselves and to others, especially when life is at its least pretty. We all want to look like we’ve got it together. Sometimes we do. Sometimes we don’t. Life gets messy. Thomas Moore, a former Catholic monk, in his book, Care of the Soul, I book I read, reread, dog-ear, highlight…in three different colors, quotes something from the Renaissance humanist Erasmus, that applies. Erasmus wrote in his book, The Praise of Folly, that “people are joined in friendship through their foolishness. Community cannot be sustained at too high a level. It thrives in the valleys of the soul rather than in the heights of spirit.”
So, from one very imperfect human, friend, wife, mother, fiddler crab God, go gently into your Monday. It’s really okay, no matter how it goes.

February 24, 2008
I will be returning soon to the evolution of my novel, Under the Pier, but given the goings-on here, I have to take some time to tell of events unfolding in the fiddler crab world.
I decided to see if it is possible to raise at least a few of Scarlett O’Hara’s and Admiral Byrd’s babies, should they survive birth. It’s a long shot, but I want to try. Scarlett looked really pregnant yesterday – that abdomen of hers is large and when she pushes at it, it’s like jelly. I have these observations again from my husband.
It is TRUE LOVE when your husband acts as midwife for your pregnant fiddler crab, keeping close eye on her while I ran out today to get a chunk of live rock for the aquarium. He even called me on my cell phone at the aquarium store to tell me that Scarlett was picking at the larval mass, pulling out a brown thread here and there and planting it in the gravel. He felt birth was getting close and I should hurry home with the live rock. I tell you, is that a friend or not? How many people would call you on your cell phone to let you know your fiddler crab is getting ready to deliver? 🙂
To back up, we went to Petsmart last night and picked up a new 10-gallon aquarium, tank top, light, light bulb, thermometer….. yes, another whole set-up. My husband is laughing but then, he is a geek, just one with different interests, so he respects this endeavor I’m involved in.
In fact, he is working on setting up his own blog that will have all kinds of tweaky things that reflect his interests. When it’s up and running, I’ll be sure to mention it. He finds the most unusual and interesting things out there. To give you a sample of the man, when we are out on a date it is not unusual to walk through the parking lot and have him explain to me the mechanisms for the inner workings of car backup lights and such. I just love it. Going somewhere with him is always interesting and an adventure. Sometime I’ll have to share how he and I hunted down the overgrown boarded up command bunker for a former Nike missile launch site in Newport News VA. 🙂 But a story for another time. Those are the kinds of dates I love. Anyway, I’ll let you know when his geek site is up and running.
To get back to fiddlers, I spent last night setting up the tank. This time I started with distilled water. We have a small water distiller and I proceeded to use up our drinking supply to make up salt water for the “nursery tank.” Mixed up Instant Ocean powder in the distilled water, set up the filter, and within a couple of hours, got the water parameters just about where I wanted them: pH 7.8, alkalinity 180, hardness >300, chlorine, Nitrite, and nitrates all zero. Salinity was about 1.008, a little lower than I wanted because I want this tank’s water to be an almost exact match for the main tank.
This morning I used some marine buffer to bump the pH up to 8.0 and alkalinity closer to 300. Added a bit more Instant Ocean to get the salinity up to 1.010. I seeded the new filter with a strip of “very well colonized” filter material from the old tank to jump start the nitrogen cycle, and brought home from Fish Pros the MOST amazing chunk of live rock – ALREADY had all kinds of marine invertebrates and microscopic algae on it because it had been in another tank that had just been dis-assembled. So, the live rock is well underway growing organisms and probably has another dose of nitrogen-fixing bacteria ready to go.
I debated about what to do with Scarlett O’Hara, leave her in the old tank and struggle with where to release her babies or put her in the new tank with plenty of room for all. Finally decided to take a chance and I’ve moved her into the new tank. She seems to be doing okay in spite of being rattled by being moved. I’m hoping it didn’t disturb her too much. It always shakes them up a bit to move them around. I have done my best to make her a good nursery and here she is free from Admiral Byrd’s claw-waving. I even took the heater from the old tank and gave it to her in the new one. I ordered a new heater for the main tank which should be here Wed. But I figured Melanie Hamilton and Admiral Byrd will be fine for a couple days with the tank lights to keep them warm. I figured “momma” needed it more.
By the way, the tank heater I use is a small one geared for 3 gal aquariums. It’s pre-set and can be mounted sideways with suction cups, and there’s no risk if it touches the gravel. It’s a Marineland Shatterproof Heater (10 watts) part number VTMD10 and found it online at That Pet Place. Since my tanks are only a third full of water (to allow space for the crabs to get out in air), regular heaters won’t work. Not enough water for them to be fully submerged. And regular heaters are generally large and have to be vertical. This guy is short and can be sideways. Keeps the tank in the range of about 78-80 degrees F. So for what it’s worth.
So…the nursery is up and running. So very much hoping that 1) Scarlett will do okay in the new tank; I would feel terrible if she doesn’t make it because of the move 2) the babies do okay.
Then all we have to worry about is how to sell off many many many many many grandchildren? 🙂 I’ll keep you posted.
By the way, if you want to have a few seconds of just staring at some nice marine creatures swimming amidst coral, click on the Instant Ocean link above. Neat intro.

February 23, 2008
So you’re like me and you’ve got a pregnant female fiddler crab. Now what?
Well, we just came home from Petsmart with a second 10-gallon tank, lid, light, and pump/filter assembly so I can set up a saltwater aquarium in which to put the babies. Maybe I’m crazy for trying to see if I can raise them …?then sell them? but the challenge of motherhood calls. My husband, a geek of a different nature, respects this need in me to see if I can do this. He quietly acknowledged that he would “understand and be willing to fund” a second tank for the “kids.”
The dilemma now is did I wait too long to get it set up and get the “nitrogen cycle” started before she releases the babies? I can take a patch of the filter gauze from my current tank, which is loaded with nitrogen-fixing bacteria, and put it in the new filter to “seed it” with bacteria.
Tomorrow I’m going to Fish Pros in Raleigh NC to get another good-sized chunk of live rock. Between the filter seeding and the live rock, that should get the water parameters in the safe zone and the bacteria up and running quickly. Also the live rock will provide calcium for the many molts the little ones will need to go through.
What I was not sure though was how I would be able to “catch” the babies since I won’t know when she releases them and I won’t know if they’ll be too small to see once she does. Also, should I make the second tank a regular “salt-water” tank to represent the “open ocean” like most fiddler babies go to, or make it brackish like what they’ll end up in? This last question got further complicated by the information I found on the blog below that indicates I should isolate mom before she releases the young. So I have much to ponder tonight while I get this up and running.
I did a search for info on pregnant fiddler crabs and come up with The “Dear Blue Lobster” blog entry” from July 25, 2007. The Dear Blue Lobster site claims to have been answering “your crustacean questions since 2002.” This entry is from someone who is concerned that her fiddlers make have “hooked up” and now what should she do? She is freaking out at the prospect of a 100,000 babies in her tank.
The gentleman who runs the blog gave good technical advice on taking care of the pregnant mom, saving the larval babies, raising them, and even indicated how much/lb. you can sell fiddler crabs for over the internet. The crustacean guru also gave the following emotional advice:
“So what do you do if your female is indeed pregnant? Comfort her. Her man has kicked her out and will no offer care for her children — in fact, he may try to eat them! ….Good luck to you and your Fiddlers. Motherhood is a special blessing indeed.”
Since it is well past July 2007….I wonder how the mom (human) and the mom (fiddler crab) made out with their situation? For myself, we shall see. I am off to set up the tank. I guess I’ll set it up brackish and isolate mom before she “delivers.” I have also emailed Dear Blue Lobster for help on what I should do. I’ll keep you posted on his reply.
I recommend the blog. The crustacean guru is Christopher Chimwish. His site description is as follows:
Christopher Chimwich received his MMN in 2000, specializing in decapod behavior. He is currently surveying benthic decapod populations in the Indian Ocean for his doctoral thesis. Chris answers questions about crustaceans, covering everything from DNA mutation in African crayfish to Fiddler crab sign language.
By the way, if you want to be a real geek, apparently the term for my fiddler crab when they have the brownish eggs attached to their abdomen is being “in berry.” So.
If you want to know what he has to say about fiddler crab sign language, click here.
