1 Chromis and 1 Damsel? And maybe in a few weeks or months I may get a clown and a Tang, who knows but currently I am feeding them "Spirulina Enriched Brine Shrimp" made by San Fransico Bay Brand in a freeze dried green pouch. And 3 snails and crabs that are doing fine on their own. Is it even necessary to change the menu with flakes, pellets, etc??
