🐠 Barrier Reef Chromis (Chromis atripectoralis)
A Subtle Silver-Green Body With a Dark Axil Marking • A Classic Schooling Fish Seen Across the Great Barrier Reef • Energetic, Constant Open-Water Movement
 
📋 The Barrier Reef Chromis, also known as the Blackaxil Chromis, is a classic Indo-Pacific damselfish widely seen schooling above coral reefs, including the Great Barrier Reef, with a subtle silver-green body and a dark marking at the base of the pectoral fin.
It comes from shallow reef slopes and lagoons across the Indo-Pacific, naturally forming loose schools in open water above coral. Every Barrier Reef Chromis we ship is feeding well.
Unlike many damselfish, this is a peaceful schooling fish that thrives in groups, displaying calm, synchronized swimming rather than territorial behaviour. Its constant midwater movement makes it an energetic open-water swimmer that adds motion and balance to a reef display. It's fully reef safe and well suited to stable marine aquariums. It reaches 9-11cm, so a 120L tank suits a group well.
