I feed mine chopped shrimp and crab which I buy at the supermarket, chopped up finely and frozen at home. I thaw a little bit at a time in a 1/2 cup of tank water along with some frozen mysis shrimp bought from the lfs. I feed about every other to every 3rd day, once or twice a week I add frozen cyclopleeze to the water mixture also. Some of the fish suck this up and it also feeds some of the corals in the tank:
He also nibbles at the algae sheets I feed my tang....
Very easy fish to keep.
Love my flame hawk fish! He adds personality and color to my tank. Also movement in other areas some fish don't swim at, different heights, levels etc. He's been a great addition to the tank. Minds his own business .......
