    Could someone help identify why I get so much poop in my tank, it looks like crayfish is pooping too much, and it feels like she always goes to the same spot to do his business and then goes back hiding under the log. I also noticed some shell loss on one of her claws, she is overdue for molting, an I don't know why she isn't. Water seems fine to me, but is there something I should add to the water to make the conditions better for her to molt? I have two dwarf gouramis in there so I can't make the water too hard.

    I feed her placo wafers and crab cuisine.

    She is about 3.5 ~ 4" long.

    Are you sure that it's the cray doing the, ahem, business? Cause that looks a whole lot like fish poop to me.

    A picture of that claw would go a long way, my first thought is she's not getting enough calcium feed her some spinach and cooked broccoli stem but a photo is needed to see if there is an excolital problem, they've all got to poo its all part of you filtering and bacteria thats needed in the tank to keep things healthy stable

    Here is a picture. When I drop the crab cuisine, greedy gouramis eat them before cray gets her chance to finish them. I think they are the ones overeating and maybe pooping too much?

    He as a bacteria disease called Rust spot/black spot
    Burnt spot there are several names for it but yours looks like the Chitin/shell as been breached which leads to secondary infection, normally caused by poor water conditions, chemicals in the tank, high Nitraits, stress. If it spreads into its gills she will die and could still if untreated you need to treat with Lavamisole asap to halt the disease, she will probably loose that claw if she gets through the next moult, big water change needed but before that a full water check needed Ammonia/Nitrits/Nitraits/gh/kh/Ph to start and find out where this as come from, as for feeding use a long tweezers and drop a pellet close to her hide as possible at lights out, you need to act on this or you will loose her

    @PTVinnyMac take a look at the body on this one I wonder if the body on yours is naturally changing colour as she ages or it is a bacterial infection which needs Lavamisole

    She is naturally red and white and the claw has always been red, however the area where you can see as darker red looks thinner than rest and definitely feels like lost some exoskeleton. I should seperate him from the fish, do you think it's better, I have another cycled clean tank I can move her to, and treat her there. I believe she is not happy with the gouramis they might be tormenting her time to time because they always steal her food. Would moving her to another tank cause more problems? Her enviroment would remain the same (hiding places, etc). Do I just taker her from one and drop in the new tank?

    Where can I buy the medicine?

    That's the best thing to do put her in a tank of her own and treat that wound. When did she last moult, you will.have to google for the med if its available in your country, where are you. Put her in a container with Aquarium water and acclimate like you would fish do it s bit longer

    I had to import Lavamisole from the states so its available to you, you can also give him some cooked broccoli stem or spinach leaf blanched for 40seconds. Stress being with the gourami's would not be helping, when did she last moult

    Her last molt probably was 6-7 monts ago maybe more. She had eggs after she molted once, they were duds, so I am not sure if she spent a lot of energy on those eggs.
    She also loves to carry gravel from one corner to somewher else and just hide sit there on bottom glass. She seems active, and she does fight for her food by just snapping at gouramis, but she never hurt them.

    Will drop some broccoli in there asap.

    Could you give me some suggestions on how to transfer her? Just move from one tank and drop her in the other? Temps are identical since identical heaters run in both tanks. Other tank is much cleaner since there is a single minnow in there.

    Even though the tanks are the same I would put her into a container with her Aquarium water and add water from the new tank gently over an hour this will help her get used to anything different in the water, this is only a precaution she would probably be ok moving her straight over, choice is yours really. Itx a long time for her not to moult, how old is she,,?
    Mine prefer sand he moves the whole tank like a bulldozer then sits on the hole or berry's the old molt to feed on later

    We have no idea how old she is, when we bought her, she molted soon after and had eggs soon after that too, I wanted to move her yesterday but she didn't want to come out and I didn't want to push her too much, I'll do a water change today and move her the way you suggested.

    I don't know how long these live but when I bought them one person said they grow up to 4" if so she might be too old to molt because she is up there, another person said they grow as much as the space given (made no sense). When I got her, the tank in store had her labeled as ghost crayfish.

    Which ever way you do it she'll be better off in her own tank to treat that claw, if her cave as a bottom put your hand over the front and lift her straight out

    No, cave doesn’t have bottom, that’s why I didn’t want to snag it over from her. She is super fast too, she gets spooked easily. When she moves I am worried she is going to hurt herself because she can't see where she is going since she moves backwards really fast in one swift move. I might just pick up a PVC pipe from home depot and use that. They can't pinch fingers too hard, right?

    If your gentle just pick her up on the carapace her claws will come up but wont reach be behind and needs a firm grip, she won't nip, if you put a container just behind her and put your hand in front she'll go back into it, she may make a few darts backward that's natural but she will run out of steam
