Chromis viridis
The Green Chromis, *Chromis viridis*, is a popular and peaceful damsel known for its vibrant iridescent green to blue coloration. This schooling fish adds a splash of color and activity to any marine aquarium.
A minimum tank size of 30 gallons is recommended for a small group of Green Chromis. They appreciate plenty of live rock for hiding places and open swimming areas. While generally peaceful, they can become territorial towards conspecifics in smaller tanks or if not kept in a group. They are considered reef safe and will not typically bother corals or invertebrates.
Green Chromis are omnivores and will readily accept a variety of foods. Their diet should include high-quality flake and pellet foods, as well as frozen foods such as mysis shrimp, brine shrimp, and spirulina. They will also graze on algae in the tank.
In a home aquarium, Green Chromis typically reach a size of about 3-4 inches. They are relatively easy to care for and are a good choice for beginner to intermediate aquarists. While breeding in captivity is possible, it is not commonly achieved in home aquariums. There are no easily distinguishable visual differences between males and females.
