The Blue and Gold Damselfish is two-tone in color with electric blue primarily on the top portion and bright yellow on the bottom and posterior portion. There is a considerable species variation in the amount of yellow on the body of the fish.
A favorite of reef hobbyists, the Blue and Gold Damsel requires a 30 gallon or larger aquarium with numerous hiding places. It can be confrontational towards its tank mates.
The diet should consist of a variety of meaty foods, herbivore preparations, and flaked foods.
