How can you tell red claw crabs are dead?

Answer:

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.
