Im back.... my previous thread was kinda long already so i decided to create a new one shorter with couple of questions to be asked again about cray's...
since i am using a 5 gal tank with my cray and i know its over stocked... i am still thinking of the cause why He is not acting normal...
i thought about molting..
my cray's might wanna molt
but since i have a small tank..
he waiting to get to a bigger tank then molt?
can they delay molting?

is that possible?

I think Cray Fish might to be able delay molting. It is often very hard for them to molt out of their exo-skeleton. I believe 32% of all Cray Fish deaths are they can't molt out of their skin. So if it looks like he is having a hard time, he might die.

32%?

They are able to drop limbs in order to get themselves free of the old shell. This will happen if the cray is disturbed (threatened) during the process or if they get stuck.

I think the cray is stressed and that's why it's acting weird.

guys i bought another young female crayfish. about 2 inches length.
She is acting normal..
they are both in the same tank.
My male old crayfish never ate since i bought him.
but this small female one is so active she eats alot..
what do you think might be the problem???
my theory is the older one is showing signs of nearing to molt.
crayfishes don't eat when they are about to molt right?
and He don't come out of his cave.
but when the small female crayfish arrive in the tank.
He comes out now.

I don't know what wrong with the old one.
isnt he is only looking for a tank mate of his own kind?


thanks.

Crays, as far as I know, don't want, nor need, and rarely tolerate other crays as tankmates. He might be even more stressed now and he might be coming out to attack her, not to be a good neighbor. Please rehome that new cray immediately or you're likely to end up with one, possibly two, dead crays.

I've moved my crey from a 10 gallon to a 5.5 gallon today, and he's acting weird, just sitting in the corner not really moving and kind of curled up. Had to poke him to make sure he was still alive.

Keep us posted.

I thought so, but in your first post you mentioned a 5 gallon so I was confused. There's a good chance you may run into problems with 2 crays in a 20. Each cray should have at least 20.

Crays, and shrimp, molt as they grow. If your cray hasn't molted, it's because it hasn't grown. I wouldn't think they can purposely choose not to molt, but I could be wrong. But in any case, you'll need to figure out why the cray hasn't grown and fix the problem.
