Overview
The Ternate Chromis is a small, hardy schooling damselfish with a soft grey-brown body and subtle yellow tones toward the tail, sharing the same easygoing temperament that makes chromis such a popular choice for reef aquariums. Unlike many other damselfish, chromis species are known for their calm, non-territorial nature.
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
Ternate 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 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.
