They are definitely eating as my snail population is down and there are empty snails shells littered all over my tank. Also of the six decorators, three have been eaten and so have a few of the hermit crabs. When I found her last night you can see a few empty shells in her den with her. they both maybe in the same den. I will try shimp on a stick later tonight. I gave them all to Legs so i have to get more.
