Chicago, this anemone isn't a host species and can eat small fish. I had one many years ago, and they are very hardy. They do tend to move until they find a place they like. They will attach to the inside of an empty shell sometimes or plant their foot in a hole in the live rock. They are easy to feed and will accept small pieces of the usual foods. If I were you, I would feed mysis, very small pieces of silverside or squid once or twice per week.
