Mine eats anything and everything. Krill, shrimp, squid, clam, bloodworms, blackworms, silversides, prime reef, brine, predator formula, mysis, flake, etc. You get the idea. They aren't picky at all. If you feed brine/mysis/silversides, it is a good idea to soak them in zoe or selcon. It is actually a good idea to soak food about twice a week in zoe or selcon. Bo
