The Green Chromis (*Chromis viridis*) is a quintessential reef aquarium species prized for its shimmering blue-green iridescence and peaceful schooling behavior. Native to Indo-Pacific coral reefs, this hardy damselfish thrives in groups of five or more, creating dynamic movement and visual depth in established marine systems. With minimal territorial aggression and adaptability to varied water conditions, the Green Chromis serves as an ideal choice for both novice and experienced aquarists building community reef environments. Their active swimming patterns and striking coloration complement SPS and LPS coral displays while maintaining compatibility with most peaceful tank inhabitants. Chromis viridis (green chromis) is a species of damselfish. Individuals tend to be iridescent apple-green and light blue, and reach a maximal length of 10 cm.
