Chromis viridis - Bluegreen Chromis
3.9 in. (10.0 cm)
Minimum Aquarium Size
55 gal. (208 L)
Reef. Provide plenty of suitable hiding places.
Foods and Feeding
Feed meaty and vegetable foods at least twice a day. Color-enhancing foods can help it maintain its bright colors.
Unlike many damsels, this species can be housed in groups. Group members will form a pecking order, with subordinate members often receiving an unequal share of maltreatment from its kin. If the chromis group is large enough (six individuals or more), the aggression will be spread out so that no one subordinate gets to much abuse. It is usually no threat to its tankmates. Large adults could pick on smaller, passive tankmates, but this is rare. It is not a threat to invertebrates and may help corals by swimming among their branches, encouraging circulation within the coral colony.
This species will spend most of their time in the upper layers of the aquarium. It looks good and they can act as dither fishes. Many reef fishes cue in on the activity of their neighbors to determine if it is safe to come out from hiding.
