Does anybody know why my crab is eating my snails.

Some crabs have a habit of doing that, some more than others...what type of crab is it?

Steve

I have a common hermit crab.

perhaps the snail had died first and the crab is just cleaning things up.

Thanks for telling me now we dont have to get ride of him

Sometimes crabs will kill snails to acquire new shells to live in. If your crab did kill the snail, that may be the reason. Do you have spare shells for the crab (not that it matters...the crab might still kill the snail)?

Yes i do have other shells for him to move into
