The Blue Sapphire Damselfish originates from Indonesia, and is a brilliant blue coloration with black outlined fins. This species can quickly turn completely black when stressed which allows them to evade predators. Like many of the other damselfish within the Chrysiptera genus, it can become aggressive towards slower moving tank mates. Be sure the aquarium has plenty of live rock for territories and hiding.
The Blue Sapphire Damselfish is hardy and is a good fish for beginners. They also make an ideal companion fish for a saltwater aquarium of over 30 gallons, and are safe with corals and invertebrates. As the fish matures it may become aggressive, causing problems with the selection of other species of fish added to the aquarium. If keeping with other damselfish, provide plenty of live rock with multiple hiding places to break up territories and decrease aggression.
The Blue Sapphire Damselfish's diet should consist of quality flake foods, frozen meaty foods such as brine or mysis shrimp and occasionally dried seaweed offered on a feeding clip.
