Common name: Trispot chromis

General information

The Three Alpha Chromis, Chromis trialpha, is a small and peaceful member of the damselfish family. It is known for its striking coloration, typically a blend of blue and green hues that shimmer under aquarium lighting. This species is relatively new to the aquarium trade and is appreciated for its schooling behavior and ease of care.

Care

Chromis trialpha is a hardy species that adapts well to life in captivity. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. A group of these fish will establish a hierarchy, so it's important to have a large enough tank to accommodate their social structure. They are omnivorous and will accept a variety of foods, including small pellets, flake foods, and frozen or live brine shrimp.

Reproduction

In the wild, Chromis trialpha are known to spawn in groups, with females releasing eggs into the water column to be fertilized by males. In the aquarium, breeding is less common but can occur if the environment is stable and the fish are well-fed. The eggs are pelagic, meaning they float with the currents until hatching.

Habitat

Chromis trialpha is found in the Western Pacific, particularly around the Coral Sea. They inhabit shallow reefs and lagoons, often found in large schools hovering above stony corals or branching corals. In the aquarium, they benefit from a reef environment with live rock for shelter and territories.
