Mine did great until it ran out of all the tiny feather dusters in the zoa frag tank. I then bought mussels, cracked the shell to make a hole about the size of a dime and then put in tank. It went nuts over it. I then filled an old shell with some mysis and dropped that in. That is how I got mine eating.Such tough little buggers. Sending good vibes
My lfs used clams for one. Small clams he would open clams up and toss them in the tank on a half shell
