I feed mine a homemade mix of mashed in the blender, oysters, clams, shrimp, spirullina flakes, formula 2 pellets, chunk of cyclopeze, chunk of ova and a few drops of selcon. I feed all my fish this mix. The corals like it too. I put it into a 1 gallon freezer bag, flatten it out and break off and feed as needed. Cheaper and possibly more nutritious than a total commercial feed. Provides, herbivores, ominvores, carnivores and corals with what they need.
