My sebae will eat anything. I bought a few more turbo snails the other day and accidentally dropped one on the nem and it was gone within minutes and the shell appeared right beside him the next day. The nem is very docile with all the fish though, they all hang out there (bangaii, chromis, clowns and damsel, sometimes even the cleaner shrimp) we call it the public anemone
When I target feed him he loves the squid!
