The hermit crab. It occupies a shell just large enough to fit its body. When it outgrows its current 'home', it searches for a larger one.
A crab that lives in the shells of other shell fish is called a hermit crab.
Shell fish are more like hermit crabs living in a shell, crayfish are like mini lobsters....Crayfish, Shellfish, Jellyfish and Silverfish are not real fish!The answer is NO.
I think that the larger fish eat the crabs when are out looking for a shell ,shell-less. But also it is possible to have a smaller fish eat a crab shell-less depending on the size of the crab.

Depending on the species of crab, its food source will vary. Crabs eat algae, water plants, small fish, other crabs, shell fish, and some will eat dead fish or decaying vegetation.
some put a enineme (spongy animal that looks like a plant) and move around, this animal stings other fish that come to the hermit crab. the sponge thing get food and the hermit crab can get protected. I really wanted to say that but the crab uses it's shell for camoflouge while it sneaks up and eats stuff.
There are a huge number of differences between a crab and a fish including the fact that most fish do not have a hard shell or carapace while most crabs do have this type of covering. Crabs also have legs and claws while fish do not have those appendages.
