Overview: The Green Reef Chromis is renowned for its iridescent blue-green body, adding a splash of color to any marine aquarium. This species is native to the Indo-Pacific region, inhabiting coral reefs and lagoons where it forms large, dynamic schools. Its peaceful nature and hardiness make it an excellent choice for both novice and experienced aquarists.

Care Tips:

• Tank Setup: A well-established aquarium with ample live rock provides necessary hiding spots and territories. While a single specimen can be kept in a 30-gallon tank, a group of six or more requires at least a 55-gallon aquarium to accommodate their schooling behavior.
• Feeding: As omnivores, Green Reef Chromis thrive on a varied diet that includes high-quality flake foods, frozen mysis shrimp, and finely chopped seafood. Feeding 2–3 times daily supports their active metabolism.
• Compatibility: Generally peaceful, they coexist well with other non-aggressive fish and are considered reef-safe, posing no threat to corals or invertebrates. Maintaining them in groups helps reduce stress and encourages natural schooling behavior.

Fun Fact: In the wild, Green Reef Chromis are known to spawn over sand and rubble substrates. Males prepare nests and guard the eggs until they hatch, showcasing their unique reproductive behavior.

By providing appropriate tank conditions and a balanced diet, the Green Reef Chromis can be a vibrant and engaging addition to your marine aquarium.
