| Varieties: | No cultivated strains — the wild-type fish is what is sold, and its shimmering blue-green is structural rather than pigmentary, so it shifts with the light and the angle. The species is inexpensive and widely available, collected across a vast Indo-Pacific range. The genus Chromis contains a number of aquarium species that are easily confused. C. viridis, this fish, is the green chromis. C. cyanea, the blue reef chromis, is Caribbean and a deeper blue. C. atripectoralis, the black-axil chromis, is nearly identical to viridis and distinguished by a dark spot at the pectoral fin base — the two are routinely mixed in shipments. All are peaceful schooling damsels and all can be kept the same way. Among damselfish generally, the Chromis are the peaceful branch and the Dascyllus and Pomacentrus the difficult ones. |

Blue Green Chromis (Chromis viridis) is a species of fish in the family Pomacentridae. It is native to Indo-Pacific reefs. The blue green chromis is the cheapest way to put genuine movement into a reef tank. It is a damselfish that never grows into the damselfish problem: peaceful throughout its life, shimmering blue-green, and reliably gregarious, forming aggregations around Acropora coral heads in the wild where it finds both food and shelter. It reaches 10 cm and ranges across the Indo-Pacific, on coral reefs and lagoons between 1 and 12 metres. It is inexpensive, hardy and long-lived at eight to fifteen years — and it schools, which almost nothing else in a small reef tank does. Odd-numbered groups are the convention, in tanks of at least 110 litres.
