Kupang Damsel (Chrysiptera hemicyanea)

The Kupang Damsel is also known as the Kupang Blue Damselfish, the Kupang Demoiselle and the Goldtail Demoiselle. It is confused in naming with the Azure Damselfish (Chrysiptera hemicyanea), which is yellow in the pectoral and anal fins, but not in the tail. It is bright blue, with a yellow tail that fades to clear at the edges.

The Kupang Damsels are very popular and are a good beginner’s fish. They eat a wide range of foods, withstand poor water conditions, are disease resistant and they are inexpensive. They are often used as the first fish introduced to a new tank. A tank of at least 100 gallons is recommended, but it is possible to keep a single Kupang in a smaller tank if there aren’t many other inhabitants. Although Kupang Damsels are among the least aggressive damsels, they still should be provided with plenty of hiding places and kept either alone or in groups of 4 or 5 in a large tank to reduce aggression.

The Kupang Damsel is particularly hardy and many hobbyists will use them to cycle a new tank. Using them to cycle tank is not recommended because it is very cruel to the fish. A better, more humane way to cycle saltwater tank would be to use live rock. As always, do not keep them with fish large enough to view them as a nice snack.
