Overview

The Purple Chromis is a small, hardy schooling damselfish with a deep blue-purple iridescent body, closely related to the more commonly seen Green Chromis but offering a richer colour tone under reef lighting. It shares all the same hardiness and peaceful temperament that make chromis such a popular choice for reef aquariums.

Like other chromis it's naturally a shoaling species and shows its best, most natural behaviour when kept in a group rather than alone, moving together in loose formation through open water.

Its affordability, resilience, and calm nature make it an excellent choice for both beginner reef tanks and as a dither fish to help shyer species feel more secure in the display.

Compatibility

Purple Chromis are peaceful and fully reef safe, ignoring corals and invertebrates entirely. They do best kept in a group of at least five or 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 a hardy, forgiving species that generally tolerates a wide range of conditions and acclimates quickly with minimal issues. A standard quarantine period of two to four weeks is recommended good practice, though this species is generally low-risk during acclimation.
