because it has no protection left.
After it molts, a crayfish needs some time to grow a new and larger shell. During this time it has no shell to protect it from attack, therefore it hides.

After shedding its exoskeleton, a crayfish hides because it becomes vulnerable to injury and attacks from predators. The crayfish sheds its exoskeleton when it needs to grow. It can take two to three days for a crayfish to re-grow a new and larger one.
The outer covering of a crayfish is it's protection. You may notice that the shell is very hard. This protects it from preditors, that is the reason it hides, to keep itself hidden from pretitores who might attack.
if its a young crayfish and a big cichlid itll eat the crayfish if the crayfish is a adult they will pick on each other as long as the cichlid isn't big enough to put the crayfish in its mouth and the cichlid isn't slow enough for a crayfish to catch
Crayfish
In the wild, you will find crayfish eating dead fish or shrimp as well as plant material. So if you are going to have them in captivity, it is best to feed them plants such as lettuce and of course you can use crayfish food. This consists of things like pellets of shrimp or even algae. They need places to hide, luek warm water, sand, rocks, shells, water, and food.
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
