Kupang / Azure Damsel (Chrysiptera hemicyanea)
Max Size: 2 3/4 inches
Reef Compatible: Yes
Minimum Tank Size: 30 gallons
The Half-blue Damselfish, commonly known as the Damselfish, is a quick-moving marine fish with a striking two-tone coloration. Its anterior body is vivid blue while its posterior portion, anal fin, and tail are yellow. Depending on the species variation, the amount of yellow on the body can differ. In the aquarium trade, C. hemicyanea is often referred to as the Azure Damselfish, although it is sometimes called C. parasema.
This fish thrives in a 30-gallon tank or larger with ample rockwork and decorations. Due to its ability to tolerate substandard water conditions, it is a popular choice among beginner hobbyists. Juvenile Azure Damsels can add color and excitement to most marine aquariums when kept in small groups. As they mature, they can become territorial, so it's best to keep them with other semi-aggressive fish. However, in larger reef aquariums, this is usually not an issue as long as there are enough hiding places available.
To maintain optimal health, the Azure Damselfish should be fed quality flake foods, frozen meaty foods such as brine or mysis shrimp, and occasionally dried seaweed offered on a feeding clip.
