The Blue Green Reef Chromis is easy to care for, beautiful, and peaceful. In fact, Chromis viridis is one of the preferred marine reef fish amongst aquarists, regardless of their experience level. This member of the Pomacentridae family is most recognizable by its gorgeous light blue dorsal side that slowly fades into a majestic pale green belly. The Blue Green Reef Chromis is desirable not only for its beauty, but also for its peaceful demeanor (despite its designation as a true damselfish) and ability to be kept with almost all other community fish, invertebrates, and corals.
