A member of damselfish family, the Blue Green Chromis fish (Chromis viridis) is a peaceful inhabitant of saltwater aquariums. With an iridescent, light blue-green colored body, Blue Green Chromis are gorgeous fish to keep in a saltwater aquarium and prefer being kept in a small school of 3 to 5 individuals. The Blue Green Chromis is reef safe (it won't eat the reef invertebrates) and gets along with most other fish.
The Blue Green Chromis is a relatively inexpensive, easy to care for, and hardy saltwater species. Although a smaller reef species, Blue Green Chromis fish are active and inquisitive, so they are generally out and about in the tank. For all these reasons, the Blue Green Chromis is a great choice for beginners looking to add color and flash to a saltwater aquarium.
