How can tell if pet crayfish is dead?

Answer 1

As crabs have an exoskeleton, they shed their shell when growing. If the shell is hollow then do not worry your crabs just grown a little bit bigger! Crabs are notoriously good escape artist, so it’s not uncommon to find them dried up outside of the aquarium.

Answer 2

If your hermit crab has just dug and hasn't resurfaced there's a good probability that it's either a digger (a crab that just likes to be under the sand) or it's molting, in which is could stay down there in either case for over a month. If your crab is on the surface, picking it up will prove whether it's dead or not. Hermit crabs that are dead will just slip out of the shell when you hold them upside down.

If the crab has dug and hasn't come up it's very important that you not bother it. This will cause it to stress out.

Answer 3

When they arent as active, and not eating. But it might be wrong, they might be molting (they get bigger). Another way is, Does your tank smell weirder than usuall? when they die, they stink.

Answer 4

They are usually moving all over the cage. If the hermit smells fishy, falls out of the shell when picked up, or doesn't respond to a gentle touch to it's antenna, it's toast.

Answer 5

If it falls out of it's shell, and is limp, lifeless, and smells "off", then it is dead.

Answer 6

You can tell if a hermie crab is dead by smelling the tank, if it smells like dead fish then a hermies dead...

Answer 7

If it stops moving
