Native Habitat and Species Information

Green Reef Chromis native habitat, distribution, behavior & aquarium compatibility.

The Green Reef Chromis, is an excellent schooling fish and should if possible be kept in groups of 5 or more individuals. Green Chromis are found in many reef aquariums, due to their bright colors and extremely peaceful nature towards both other fish, corals and invertebrates. This species is also an excellent choice for the beginning marine aquarist as they are a very hardy species and will tolerate less than perfect water conditions.

Green Chromis are also very easy to feed as they will readily consume most marine fish foods on the market including flake and fried dried. While this species is not difficult to keep in the aquarium environment, it is a very rewarding species as they bring a lot of activity and bright colors to either fish only or reef aquariums.

As the photos of the Blue/Green Reef Chromis show, they can vary in color from blue to green depending on the lighting and distance from the lights. While the Green Reef Chromis has a pretty standard body shape, they more than make up for this with their vibrant coloration and active swimming style. This species especially shines when kept in small groups where their schooling and bright coloration will add to their visual appearance.
