🐠 Green Chromis (Chromis viridis)
An Iridescent Blue-Green Shimmer Shifting With the Light • A True Schooling Marine Species • One of the Most Peaceful Damselfish Relatives Available
 
📋 The Green Chromis is a small, shimmering marine schooling fish prized for its iridescent blue-green colouration, gentle temperament, and constant, lively movement throughout the upper reaches of the reef aquarium.
It comes from shallow lagoons and coral-rich reef flats across the Indo-Pacific, typically found in large, loose aggregations hovering above branching coral, darting in unison to feed on plankton drifting in the current. Every Green Chromis we ship is feeding well.
Naturally active and social, this is one of the most peaceful damselfish relatives available in the trade, a rare combination of schooling behaviour and a reef-safe temperament. Kept in a proper-sized group, its synchronized movement and shifting colour in the light create one of the most visually rewarding schooling displays in a reef tank. It reaches 7-8cm, so a 115L tank suits a proper school.
