O.S.I. Micro-food is a specially formulated diet for baby fish and marine reef invertebrates. Invertebrates and baby fish require food with a high fat level and very small particle sizes. In the wild, baby fish and many invertebrates feed on natural plankton. O.S.I. Micro-food is an artificial plankton with a 100-micron particle size. The high fat content provides energy-rich food particles to promote growth in baby fish and support the slow feeding habits of reef invertebrates.
