I feed my fish once a day, sometimes twice. Usually in mornings before lights come on I feed them flakes and pellets. In afternoon w/ lights on I feed them a mix of mysis, brine, silversides, ocean plankton, formula 1 and 2.
I also put algae sheets in the tank almost every day or at least every other day.
I don't know what else to do for the guy. I've had him for a year almost and in my old tank it never touched corals. It only picks at my plate and elegance coral, and from what it seems, both corals will not survive.
