I feed mine twice a day, although some days they get just one feeding. I try to vary their diet as much as possible. Enriched mysis is a staple. However, at times I don't enrich(varying diet). I will feed adult brine shrimp, feeder shrimp, and amphipods, when I have them. For the dwarf seahorses, I feed them bbs and they will also take the tisbe copepods (sold on this site). Jan
