Chromis - Great Barrier Reef

Overview

The Great Barrier Reef Chromis is a small, hardy schooling damselfish with a soft blue-grey body, native to Australian waters and a popular choice for adding safe, active movement to a reef tank without the aggression common in many other damselfish. Unlike some of their more territorial relatives, chromis species are known for their calm, peaceful temperament.

They're naturally shoaling fish and show their best, most natural behaviour when kept in a group, moving together in loose formation through the middle and upper water column.

Their hardiness, small size, and full reef safety make them an excellent choice for both beginner reef tanks and as dither fish to help other, shyer species feel more secure in the display.

Compatibility

Great Barrier Reef Chromis are peaceful and fully reef safe, ignoring corals and invertebrates entirely. They do best kept in a group of at least four to six individuals, showing natural schooling behaviour and reduced individual aggression compared to being kept singly or in pairs.

They mix well with virtually all peaceful to semi-aggressive community fish and rarely cause problems in a mixed reef tank.

Health & quarantine

This is one of the hardier reef fish available, generally tolerating a wide range of conditions and acclimating quickly. A standard quarantine period of two to four weeks is recommended good practice, though this species typically has few issues during acclimation or long-term care.
