My crab isn't moving, BR    1/1/08
Hello crew,
<Greetings and happy new year!>
I was wondering if you would be able to help me out. I have a crab (*Seserama bidens*), sold to me as a Red Claw Crab.
<Ah yes... now known as Perisesarma bidens, though the red-claw crabs traded may be multiple species, given that Perisesarma bidens is primarily from East Asia while most exports are from Southeast Asia and elsewhere.>
I bought it close on a month ago and he quickly became my favourite addition, roaming about searching for food and generally acting in a brazen manner.
<Quite so. These are rewarding pets when cared for properly, and well worth their own specialised quarters.>
However, I recently purchased a 30 gallon tank filled 2/3, bogwood creating a land area and a rock pile for my two crabs to hide in (the other being a golden fiddler (*Uca *sp.) ) and for my dragon goby (*Gobioides broussonetti*).
<A nice collection of livestock.>
The new tank seems healthy (specific gravity at 1.005).
that's the only real thing I measure) the guppies and platys that share it with them are doing fine, and the fiddler is quite lively. Crushed coral for substrate, java fern floating around, trying to get some pieces to take root.
<All sounds fine, though strictly speaking Platies aren't brackish water fish, though my experiences agree with yours that they do well at low salinities.>
The problem is the red claw, who used to be quite active, scavenging around his log as well as in the water, recently took to hiding. I assumed it was just molting, and after maybe three days, and no actual result, I picked out the rock he'd been holding on to from the rocky pile as he had not been eating or moving and I feared the dragon, who also likes that spot, might stress him out.
<Curious. I'd have associated hiding behaviour with moulting, too. Crabs of most sorts are potentially antagonistic towards one another, so do check there isn't bullying between the Perisesarma and Uca crabs.>
He looked just as he always did, no colour change, nothing that would indicate molting to me. As I have mentioned he used to spend a good bit of time on land, I thought maybe he just couldn't get up there now (he'd been missing a leg upon purchase, I know it's a no-no, but he was the only one left, and I hadn't really noticed till I got him home).
<A missing leg usually isn't a problem when these crabs; they're quite tough and regenerate lost limbs quickly when kept in brackish water. On the other hand, our ability to prevent secondary infections in invertebrates isn't good, given that things like copper are toxic to crustaceans even at very low doses.>
So I slipped him onto the wood and sprinkled a few bloodworms in front of him, he stayed for a while and then crawled off and fell into the water where he landed upside down. Despite much flailing he was unable to right himself, so I stuck the net in and he quickly righted himself. He's been there in the open, next to a large shell for over a day, not really moving and I still haven't noticed him eating. He's not being bothered by any of his neighbours. What do you suppose is wrong with him?
<Very difficult to say. One problem with these crabs is they're often traded as freshwater animals, and if they've been kept in freshwater at the wholesaler and the retailer, then they can lose condition. Uca crabs are much worse in this regard than Perisesarma, but it is still one more factor beyond the aquarist's control. We don't really know anything much about secondary infections or parasites of crabs. Pretty much they're either healthy or dying. If yours is going to recover, it will, but otherwise the best you can do is watch, keep the water clean, provide suitable food, and if the crab dies, remove it at once.>
My mother keeps telling me he's dead, and I try to tell her he's just molting, do you suppose this is so? He'd often sit for a while not moving before hand, but never for days! I don't really know what's typical molting behavior for crabs, I'd always thought they hid away after they molted, or during, not beforehand.
<Moulting is very obvious and usually over in a couple of days. One problem with crabs and indeed freshwater crustaceans generally is iodine. While small shrimps seem to get enough iodine out of the water or their food, larger animals like crayfish and crabs apparently benefit from iodine supplements. These supplements can be purchased from stores catering to marine aquarists as iodine supplements are widely used in reef tanks. At this point it might be too late for the red-claw crab, but any new specimens you buy, and the Uca crab as well, will benefit.>
I wouldn't think it would be a problem with my levels, as the fiddler and everyone else are doing fine. I heard a rumor of Java ferns being poisonous to fish, he ate a good chunk of one before I moved them, could that be a factor?
<Possible, though normally animals stop eating the Java ferns because they taste nasty long before they actually get sick.>
I'm just trying to think of everything here, no matter how absurd. I apologize for my lengthiness, but the instructions on your site said include every detail.
Any thoughts would be well appreciated,
-Collin
<Hope this helps, Neale.>

Re: BR crabs... Now: Specific Gravity 1.010... for Hermits, Dragon Goby...  1/2/08
Hello there,
<Hello Collin,>
I wrote in yesterday about a crab who's not up to his norm, and I will for sure be trying to track down an iodine supplement (as recommended by Neale) to help out at this stage, whatever good that will do. I had heard about this, but there is a slight lack of aquarists specializing in crustaceans or BW tanks in my area and I couldn't find anything locally on it, but I know of one place that probably has it and knows what they're at.
<Anywhere specialising in reef tanks should have this, and failing that, you could obtain online.>
But! I have another question:
I read on your site that the blue-legged hermit crab (Clibanarius tricolor) could be acclimatized to a specific gravity of 1.010
<Apparently so. Do acclimate them carefully, and take great care to identify the crabs carefully before sticking them in a low-salinity environment. SG 1.010 is at the low end of their range, and you will of course need to make sure other things like water quality are "marine standard".>
I was wondering if you could tell me if the inhabitants of my brackish tank would be fine with this level of salt, as my findings on the internet have been rather inconclusive with different authors throwing numbers around as if they were just that: numbers. There doesn't seem to be any set specific gravity that people can rely on for these animals.
<Uca and Perisesarma should be fine; both spend minimal time in the water and likely breed in the sea anyway. If you're concerned, put a small basin of plain freshwater for them to drink somewhere on the land. An upturned Oyster shell stuck in the sand would be ideal. Guppies can be acclimated to anything up to full strength seawater safely, but you must do this very slowly, over several weeks. You can actually buy "marine guppies" as feeders for marine fish. The Dragon goby will be very happy at SG 1.010. The only chap who can't be kept there is the Platy.>
Anywho, my tank has a golden fiddler (*Uca *sp.), dragon goby (*Gobioides broussonetti*), Red claw crab (Perisesarma bidens), two guppies and two platys. So I was wondering if you would be able to tell me if I would be able to house this little guy sometime in the near future with the current inhabitants, maybe rehousing the guppies and platys? Also, would I be able to add the hermit with the current bottom dwellers that are on the go in there given this is all a 29 gallon tank? I may be short one red claw crab within the next week or two, if that's a factor. (Given his current condition.
<I would imagine they will ignore each other. Hermits are too well armoured to be molested by small crabs, and since the hermit is fully aquatic, your land crabs won't encounter them much anyway.>
Though I was watching him "scratch" his claws off one another, and against his legs. I know the fiddler and red claw both came from the same tank, same store, only the red claw had been in there about a month later till I bought him, I hadn't really been counting. Could have been FW, I wouldn't be surprised, I'll ask them soon.)
<Usually these things are sold as freshwater.>
So yeah, thanks in advance for reading my email,
You guys are awesome
-Collin
<Glad we could help. Cheers, Neale.>

Clibanarius tricolor biotype  1/14/07
Hello Robert,
<Neale>
I can probably rustle up a few pictures. There are also some useful   sources on Wikipedia, which we used in my book (which I finally have   a preview copy of, by the way). So there's other options, too.
<Have the ones you sent along, thanks. Will post with credit to you>
Since you're a marine guy, perhaps you'll know whether the blue-leg hermit sold in the UK (Clibanarius tricolor) is the same as the one in the US. I've mentioned it in the article because it does well down to SG 1.010. I assume it's a rocky shore or estuarine species that gets collected as a cheap reef critter. But I don't know anything specific about its ecology. Can you enlighten?
<I do think this is the same animal/species... and yes to its euryhaline tolerance>
Cheers, Neale
<BobF, out in HI... trying to catch up!>

Fiddler Crabs   12/14/06
My son brought two fiddler crabs home from school after a class project. We have tried to learn about them from internet searches, but only recently found your web site. It has some great information!
<Ah, good... We intend to be useful (timely, accurate, significant, meaningful... in our information presentation... And always open to review, suggestions for improvement>
We've set up a small tank with aquarium gravel, and we set a 3/4" deep dish (actually the bottom of an old pencil case) in the center. We've added some plastic plants and a small aquarium feature, which the crabs seems to like to hide under. We keep gravel and brackish water in the dish. We feed them ground hermit crab pellets, bits of krill, and bits of cuttlefish bone. I remove approx. 1/5 of the water every night and replace it with fresh, and clean the tank every two weeks.
<Sounds very good>
We've had the crabs two months. At first they were very active, scurrying around the stones at night. Now they seem to spend all their time in the water, hiding under the tank features.
<Mmm, not atypical behavior. Are shy animals that don't like a lot of "commotion">
They became active again a few days ago when I cleaned the tank, but soon went into hiding again. In the time we've had them, they have not molted.
<Will do so in time... with growth>
Does this sound like normal behavior?
<Not unusual thus far>
Is there something more we should be doing?
<Do you know, have you tried to find out the name of the species you have? Some fiddlers have quite different requirements... e.g. the saltiness of their water...>
We really like the little guys and want to take good care of them. I'm not prepared to invest a lot of money in equipment, but would at least like to know what I should be doing.
Thank you for your help!
Mary
<Please consider setting your child on the task of discovering the species involved here... And write me/us back re your progress. Bob Fenner>

Re: Fiddler Crabs

Thank you! I will share your reply with my son and set him upon his research task!

<Ah, good. BobF>

Dismembered crab    11/28/06
I suspect this question will end up being mostly academic because I have a feeling the critter in question will be an ex-critter by the time I get home. I've got two red claw crabs
<Likely Fiddlers, Uca>
in a 25 gal. brackish tank that had, up until last night, coexisted just fine. They had established separate territories and mostly didn't interact at all. Well, I added some new plants last night and this morning awoke to a crab devoid of its pinchers. Completely amputated cleanly at the joint with the body.
It was flailing around upside down and couldn't right itself. I moved it back up to its territory and placed it somewhere where it was hidden and mostly upright.
As I said, I'll be surprised if it survives the shock, but if it does, is there anything I can do to help it survive until it molts and starts to get its front claws back?
<Separate it from the other conspecific crab>
I know that those claws are what it uses mainly to feed itself and it doesn't seem to have alternative legs that it uses like our crayfish do. And would adding something like Melafix make any difference?
<No to adding this or any other phony or real medicine... time, feeding, keeping the water quality constant... When the crab molts a few times, it will re-generate its missing limbs. Bob Fenner>
Sarah

Re: Dismembered crab    11/28/06
Thanks for the suggestions. And no, it's not a fiddler, it's a red claw crab, Sesarma bidens or whatever they've changed the taxonomy to.
Sarah
<Ahh, thank you for this. My input remains the same. Bob Fenner>

Brackish Fish and Crabs - 3/5/2006
I am very interested in having brackish crabs and brackish fish. I have not bought a decent sized tank yet but I want to research types of fish first. I like puffers (who doesn't) but obviously, they cannot go with crabs and the like.
<<Depends on the personality of the puffer, but you are right, as a rule.>>
I have gone on very many internet sites and they sometimes have information on brackish crabs and fish in the same tank, but only ever say top dwelling fish and short finned fish. One of the only examples of brackish fish and crabs was red claw crabs and bumblebee gobies but those are bottom dwelling! If possible, could I be told of all possible combinations of fish and crabs (in brackish conditions) including more than one type of fish to one type of crab?
<<Too many variables, you are going to have to do your own research here.>>
I like red claw crabs but would go for another like fiddlers. I would only aim at having one or two crabs in a tank. To make a more specific analysis of what type of tank I am after I would have to say an around 50-gallon tank with a lot of depth and width (not much of a tall tank person). For internal decoration and design, I would like to have a fake rock cave with its entrance facing the front of the tank so I can still see the crabs inside (maybe logs so they can reach the air not sure yet on what add so they can reach)
<<Do make sure you house the crabs you choose properly, and create a dry land area, if necessary.>>
I would really like to know some names at least of some top dwelling short finned brackish fish.  If there are no good combinations, if possible, could I be sent a table or something in which it shows what brackish fish can go with what?
<<No such table exists, sorry!>>
This is a lot to ask but it would be extremely helpful and I may have asked things against your policies (apologies if I have) but I saw that I had to type properly and I hope I did so adequately.
<<Capitalized I’s would be nice too.>>
I will not expect a question this long to get a full reply instantly and I do hope this is a free service otherwise oops.
<<It is, yes.>>
Yours sincerely and thankfully whether I get the things I asked for or not (very long message to read),
James Briscoe
<<Look into Orange Chromides; they are a beautiful low-end brackish Cichlid.  Good luck with your research. Lisa.>>

Marine Inverts in Brackish Aquaria?  - 01/03/2006
I've looked all over the web on this question.
<All of it? It's a big place.>
So ya'll are my last hope on this one.  
<I'll see what I can do Obi-Won...I mean Michael.>
I have a light brackish 29 gallon with an Archer and a Leopard Puffer.  My question is can I buy a saltwater crab and acclimate it to my tank.
<Generally speaking; no. Reef Invertebrates come from one of the most stable environments and can not adapt to such a change.>
I am willing to increase my salinity, if need be.
<Research WWM re: the proper environment for marine inverts.>
I know puffers eat crabs and snails, however mine is pretty small and well fed with lots of cover in tank for hiding.
<You'd be surprised how much damage that little beak can do.>
Maybe a larger crab or hermit?
<See above.>
Thanks, Michael
<Welcome, Adam J.>

Crabs & Puffer?  5/31/05
Howdy,
<Hi, Pufferpunk here>
I am wanting to add a brackish water crab that can stay in the water all the time in my 10 gallon tank.
A blue legged crab was a thought, but I'm not sure he can stay in brackish water.  The other part of the
problem is that I have a figure 8 puffer in there too. I'm thinking the puffer will eat a blue legged crab
even if he could survive the water conditions.  I've read plenty of websites that just say nothing can go
in with the puffer (crabs and other cleaners that stir up the sand).  For a small tank with only 1 fish, I
wanted some other small creatures to climb on the liverock and stuff.  Needless to say, snails are out
of the question.  Any suggestions?
<Crabs & snails are puffer food.  I don't suggest adding anything a puffer can eat.  There really is no clean-up crew for that tank, you'll have to do your own maid service.  In a 10g, it is best to keep the puffer alone (interesting enough tank w/just the puffer) but you might be able to get away with a couple of bumblebee gobies as tank mates.  They may get eaten though, if that is the kind of F8 you have.  You just can't tell with a puffer!  ~PP>
Thanks, Brian

Fiddler Crabs on the Lam!
I had 2 fiddler crabs, both tried to escape the tank, one did.
<Yes, they are great escape artists. Best to keep the water level down a couple of inches & keep a tight fitting lid on top, taping off any entrance for cords, etc, where they can climb to get out.>
I have read that they sometimes require time away from water but must be kept moist. I have mine in a deep 40g. tank, how often should I remove him and for how long should I keep him out of the water? Does this require a separate tank?
<A floating piece of driftwood or plant should suffice.>
I have only had these for about two weeks but would like to keep the one I have left, and hopefully from escaping! I still haven't found the other one!
<I have found them on the opposite ends of my house, from where they escaped & my dog has found a few! ~PP> 

Red Claw Crab
<Hi Anthony, MacL here. The only red claw crab I know of is actually a brackish crab often sold for freshwater. Is this what you have?> I purchased a red claw crab from a local Fish store about 2 weeks ago. I believe the crab is a female due to the very small claws.  Anyway, recently she has had her abdomen hanging open. <Maybe releasing eggs?> I figure she was getting ready to molt, but she hasn't done anything for 2 days now.
She has already molted once since we have had her and it didn't take long.  She has plenty of different kinds of food.  Also these past 2 days she is flipping herself over on her back. <Not a really good sign.>  Can you tell me what is wrong? <I'm just guessing here but I think you probably have her in fresh water and she needs some salt. I also think it might be a difference in PH as well.>  I have searched through the internet, but cannot find any information on Red Claw Crabs.  <I did a search on google and came up with tons of thing on them.  You might try www.google.com> Thank you for your time and patience. <Anthony you might do the research on them and decide if it needs to be in brackish water or not and make a decision from there.>

Rogue Crab
>Hey WWM crew.
>>Hi.
>I have a slight problem.
>>Me too, but I'm not going to talk about it right now.
>My red clawed crab has decided to take a walk on the dry side of the tank.
>>The "dry side"? As in "the outside"?
>I have spent two days looking and am at a loss as to where it is.
>>What kind of crab is this, exactly? A land hermit crab? A saltwater hermit crab? A freshwater fiddler crab? Is it a tasty crab, maybe?
>Two questions. Will it still be alive this long outside the tank?
>>I have no idea, since there are so many crabs we can be talking about, here. If it's a land hermit, and you're keeping it in a tank with NO dry areas, then it's off to find a new flat, better digs and all that. Otherwise..
>And if so, how in the HELL do I track the little bastard down???
>>Find a sexy girl crab, maybe?
>I'd like to find him before the cats do, and if he's perished I'd really rather not find him by smell.
>>What if the cats already found him, and that's why you can't?
>Any help you can pass along would be greatly appreciated. Thanks, Keith P.S. Don't tell my wife.....
>>Mum's the word! I'd start checking the kitty dumplings, myself. Marina 

Rogue Crabby FOUND!
>Dear crew, Crab found!!!
>>Hee! Great. And don't say I spilled the beans to your wife!
>More importantly, ALIVE!!! Apparently it had been living in the power filter for the last week...
>>Must like it there.
>So now, what do I do with it?
>>Scold it.
>It's not a hermit, but I don't know much more about it than that. It was sold to me as a "red clawed crab," I didn't read the scientific name. Didn't think I'd need to. Best descript. I can give is that it's about 3/4" across the back, and is shaped like a big brown Chiclet (gum), with arms and legs. It has darker brown patterning over a lighter shell, with two big red pinchers up front that are white on the tips. And it's freshwater.
>>That's somewhat helpful.
>I've offered meaty foods, but it's never showed much interest. Could it be wanting algae, or just anything that's decaying enough to be tasty?
>>That may be, or it's also wanting a private flat, a room of his own so to speak. If you don't mind it being in the filter, leave it there. If you do, then give it a hole to call home, and don't worry about feeding it directly at this point. You could try a few things, but let's try that first, see if it's happier having some privacy. When you scold it, don't wag your finger too close to those claws. Marina
>As always, any help is welcome. Keith 

Rogue Crab goes to the Rogue's Gallery
>Hey Marina, a parting note on my eight legged headache.
>>I suppose he's too small of a bit of meat to be enjoyed that way, eh?
>After much searching, I have a solid I.D., and another "fish experiment" to irritate the wife with. (Not to say she doesn't enjoy the tanks I have, she's even encouraging a saltwater project. But, She IS jealous of the time it takes
to care for, and more importantly view them. And the only reason she wants marine is because she wants, and I quote, "Nemo fish." <sigh>)
>>Oh lord, not Nemo again! (A tip, they do NOT need anemones!)
>I have discovered myself to be the proud owner of one Sesarma bidens.
>>A who? If you can possibly send in some decent pictures, we'd love to have them archived on the site.
>A fresh to brackish species from southeast Asia.
>>Ah! 
>Eats anything handy, as long as it's not moving.
>>Thank goodness for that, and other small favors.
>Not known for chasing fish, fortunately. Likes to trek out on dry land a few hours a day.
>>So he might appreciate something more resembling a vivarium, or mangrove setup.
>Smart, strong, fast, and hardy apparently makes for a notorious escape artist. But, at least I know why my filter cartridge lasted twice as long as normal, he cleaned it for me... Go figure. Looks like I'm entering the world of <GASP> species tanks!
>>Sounds like every filter needs one of these guys.
>As if my life wasn't interesting enough. Oh well, something new for the kids to poke at. Keith
>>I like the way you think. Glad to know you've nailed him down, so to speak. And thanks for the follow-up. Marina 

Brackish Arthropods and Catfish 7/11/03
What kind or kinds of crabs can live in a brackish water aquarium?  
<quite a few shrimp and crabs.. some of which are seen in the trade like ghost/grass shrimp, mangrove and fiddler crabs... none of which are compatible with your puffer which will pick their eyes out if not eat them outright>
I currently have a 65 gallon tank with bumble bee gobies, green scats, puffers, and mollies.  My tank has a sand bottom that needs some house cleaning.  Got any ideas? S/y, Carole
<The is an Albina (not "albino") Pleco that is brackish tolerant. A good scavenger and innocuous. Ships out of South America:
http://amazingrays.50megs.com/custom2.html
Best regards, Anthony>

Feeding (freshwater crab)
I just got an aquarium, my first fish was the classic gold fish
I just got two more fish and a crab, am not sure what kind but its small and has one big claw and one very small, <<Sounds like a fiddler crab, and depending which type you have may be better off in a brackish system.>> my question is am not sure what or how to feed it, I was told the shrimp pellets but it doesn't seem interested, am not sure if that's what I should be trying to feed it and if it would eat them after a while when I left it would never get a chance because the (small white fish with orange on its head) eats all the food as soon as it hits the tank <<Hmmm... most crabs are termed opportunistic omnivores, which means they'll eat just about anything they can get their claws on, which sometimes included each other, depending on the type of crab. I would ask the place where you got the crab what the Latin name is, hopefully on their shipping list, and use that to find more information about this crab. In the mean while, here is a URL to get you started: http://www.wetwebmedia.com/BrackishSubWebIndex/braccrabs.htm - and do read the FAQs beyond. Cheers, J -- >> 

hi (Collected brackish crabs...)
<<Hello...>>
my name is Samantha. <<Mine is Jason - how are you?>> I went crabbing the other day and all the crabs we caught were to small to keep. when we got home my little sister asked how long does it take for a crab to grow an inch. I told her I' find out for her . so if you could please e-mail me that would be great. bye
Samantha
<<You sure asked the tough question... for starters, crabs and their other cousins in the Arthropoda family actually shed their skin in order to grow in a process called molting. So... the real answer to your question is: It depends on how often the crab molts. This can be once every couple of weeks to once a month or once every couple of months depending on the type of crab. Even then not all crabs grow to large sizes, some stay small. If you want to read up some more on crabs, here are a couple of links:

"A Craw-Fish by any other Name would Chew Plants..."
Mr. Fenner:
I am in the early stages of preparation for building my first community tank. I am planning a 35-Gal tank with many live plants and two species of schooling middle fish, one species of surface fish, and an additional species of bottom-feeding/Pleco-type fish. Is this feasible?
<Sure>
My main concern is this: I feel that in the future I may be unable to defend myself against the irresistible charms of lobsters and crayfish. 
<They are delicious... prepared properly!>
Is there a place in a perfectly harmonic community tank for one of these invertebrates?
<Mmm, no, not really. There are some fresh to brackish crustaceans that are "better"... please read: http://www.wetwebmedia.com/shrimpfw.htm>
I hear that they have picky tastes in water pH and temperature, are destructive to aquatic landscaping, and can be determined to bust out and go AWOL. Is there a way to have fish AND Yabbies?
<Again... not really... their tastes are actually "too cosmopolitan", and many species are known to be quite "eury" condition... adaptable to widely varying conditions... but most all what folks call "lobsters", crayfish, crawdads, ditch "bugs"... are all too destructive, fish-eating to be "harmonious" in a community tank... Maybe two tanks? Bob Fenner>
Please advise.

Freshwater crabs
Hello,
I want to try keeping freshwater tropical crabs. The species that is
often on sale in the UK, small red crabs. I can't find any books or articles
on keeping them. I would like to know;
1. what they like to eat,
2. how many to a tank,
3. if I can keep a few fish with them as well,
4. how long they live,
5. what sort of tank (plants, rocks, shelter, etc),
6. ph of the water,
7. filtration,
8. how much oxygen,
9. and how simple they are to look after.
Thank you
<Hmm, I suspect it is Sesarma bidens you are referring to. Please start with this site: http://wrongcrowd.com/~aquaria/crab/
and use your search engine with the common and scientific names to find more. Some general husbandry information can also be found on our site: http://wetwebmedia.com/brcrabs.htm
Be chatting, Bob Fenner>

I just got from our pet store tiny red claw crab now I cannot find out much 
about them & how to care for them they are not hermit crabs but red crabs I 
looked up res Caribbean crabs found nothing I need to know more what they need
thanks
Sharon
>>
Not enough information, I'm afraid. Maybe call, go back to the store, and ask them to check their invoice for the scientific name of these decapod crustaceans... And do keep your eye on the crab... Some get quite big, and many are opportunistic... eaters of other livestock they can get their claws on
Bob Fenner
