The Sapphire Damsel is a very colourful, hardy, and active fish. In the wild, Sapphire Damsel are found throughout reefs, usually busy defending a small territory. The female is all blue, the male has an orange tail.
The Sapphire Damsel has the ability to hide in a hole or crevice and darken to an almost black colour. This usually happens when it is threatened. After the perceived threat is gone, it will turn electric blue in a matter of seconds.
The Sapphire Damsel is less aggressive than some Damsels, so its housing should be able to easily accommodate multiple specimens. It is a good fish for beginners, and makes an ideal companion fish for an aquaroium, and as a great companion for reefs and invertebrates. As the fish matures it may become aggressive, causing problems with the selection of other species to be added to the aquarium. If keeping with other damselfish, provide multiple hiding places to break up territories and decrease aggression.
The Sapphire Damsels diet should consist of flaked and frozen foods, and herbivore preparations.
