Green Chromis

The Green Chromis, native to the Indo-Pacific region, flourishes in coral-rich coastal waters and shallow environments, making it a perfect fit for reef aquariums. It's essential to mimic their natural habitat by providing ample hiding spaces within live rock structures. While they are reef-safe, their schooling behavior is notable, requiring a group of at least five individuals for optimal well-being and stress reduction.

These hardy fish, with an average size of 3 inches, exhibit minimal sexual dimorphism and can live up to 10 years with proper care. Their omnivorous diet includes marine pellets, flakes, and supplemented live or frozen brine shrimp and mysis shrimp. With responsible sourcing prioritized by, aquacultured specimens are available, reducing the impact on wild populations while ensuring hardiness in tank environments. Maintaining stable tank conditions, including optimal water parameters and moderate water flow, contributes to their overall health and well-being.


Originating from the Indo-Pacific region, the Green Chromis (Chromis viridis) thrives in coral-rich environments and shallow coastal waters. In captivity, replicating their natural habitat involves providing ample hiding spaces with live rock structures.

Reef Compatibility and Behavior:

Considered reef safe, the Green Chromis adapts well to reef aquariums. Their schooling behavior is a notable characteristic, and maintaining a group of at least five individuals is recommended to ensure their well-being and reduce stress.

With an average size of 4 inches, the Green Chromis exhibits minimal sexual dimorphism. These hardy fish boast a lifespan of up to 10 years when provided with proper care, making them an enduring addition to marine aquariums.

Diet in Captivity:

The Green Chromis is an omnivorous species, accepting a variety of marine pellets and flakes. Supplement their diet with live or frozen brine shrimp and mysis shrimp to ensure a balanced nutritional intake.

Tank Requirements

Maintaining optimal tank conditions is crucial. A minimum tank size of 30 gallons is recommended for a group of Green Chromis. Stable water parameters, including a pH of 8.1-8.4, salinity between 1.020 and 1.025, and a water temperature of 74°F to 78°F, contribute to their overall health. Moderate water flow replicates their natural environment.
