We are probably certain you overfeed your fish already. They are most likely pampered by frozen fish food already but Ocean Nutrition’s Freshly hatched baby brine shrimp food is a nice idea for small or delicate fish and invertebrates. One bottle contains in excess of 1.5 million artemia nauplii. Doesn’t cloud the water and developed in collaboration with the Artemia Reference Center. Expect to see this in the US very soon.
