Description
The blue green chromis is a small, brilliant damselfish from the Indo-Pacific. The species grows to about 10 cm and has a shiny blue-green body that glows bright green in sunlight. It schools in large, dense numbers just above branching coral in shallow lagoons and on reef flats and filters zooplankton from the open water; when threatened the whole school dives into the coral. Males guard the eggs and fan fresh water over them with the fins. The fish is a popular reef aquarium fish. The IUCN assesses the species as Least Concern (LC).
