Appearance

A small, slender damselfish with vibrant emerald-green coloration covering the entire body. The body is slightly compressed laterally with a forked tail. The dorsal and anal fins are translucent to yellowish, and the fish has a rounded head with a small terminal mouth.

Diet and feeding

In captivity, feed high-quality flaked foods, small pellets, and occasional live or frozen microfauna (copepods, amphipods, brine shrimp). These zooplankton-feeders benefit from frequent small meals that mimic natural grazing behavior.

Difficulty and care for the Green Chromis

Green Chromis are hardy, peaceful reef fish suitable for beginners. They are tolerant of stable reef conditions and pose no threat to corals or invertebrates, though they should be kept in groups for best behavior.
