The Green Chromis (Chromis viridis) has a brilliant green-blue hue to its scales. Green Chromis are schooling fish that are best kept in schools of at least six fish. Unlike many of the other damselfish they are peaceful and shy.

Damsels and chromis both come from the Pomacentridae family, which they share with Clownfish, a close relative and another very popular group of aquarium fish. Their temperament can range from very peaceful to quite aggressive and territorial. Chromis (fish from the genus Chromis) tend to be more peaceful than the rest but can also be more delicate. Other common genuses of damsels include Amblyglyphidodon, Chrysiptera, Dascyllus, Neoglyphidodon, Pomacentrus, Stegastes and others.

These fish are generally not picky eaters. In the aquarium, they will usually feed on flakes and pellets but should also be given fresh or frozen algae and meaty foods like brine shrimp, mysis shrimp, planktons, krill, shrimp, scallop and similar items.

Damsels can become very territorial as they become established in the aquarium. Some species will defend their territory especially aggressively; use caution when stocking the aquarium since their small sizes can be deceiving; mature or established damsels may pick on smaller or weaker fish or on new arrivals. Some damsels retain the same appearance throughout their entire lives while others undergo a radical color change as they mature from juveniles to adults. A few may get more colorful as adults but most change from very colorful juveniles to bland, more subdued adults.

Pretty Fish


We ordered 7 of these fish and 3 arrived dead. The other four died one a day after that. Our money wasn't returned with the 5 day or Arrive Alive guarantee because we were told that this fish "doesn't ship well." Well then why even offer to ship it at all? If it's not even likely to survive to the point that it's not guaranteed to even be delivered alive, it seems like this fish should only be offered for in-store pick up. The fish were very pretty under the light in the aquarium, it's too bad they only lasted about 4 days.



The chromis I purchased were great. Be prepared to lose a few chromis (which occurs wherever you buy chromis) so order a few extra. The ones I received were very beautiful and added a lot of activity to my tank.
