My clown fish eat everything, if it is not too big a piece. The best is a variety, including mysis, brime shrimp and spirulina. They also eat flake food. A good quality flake food they like is called PE flakes by piscine energetics.
LRS Fish Frenzy is good, but I find that many pieces are too big for them. They spit them back and the Tang and Rabbit fish eat them instead.
a varied diet is always best.
i feed TDO Chroma boost pellets 2x/week, and LRS reef frenzy 3x/week. hikari could definitely work but i would add pellets or flakes in the mix
