Chrysiptera parasema, also known as Yellowtail Damselfish or Goldtail demoiselle is a popular saltwater aquarium fish from the Indo-Pacific.
A small marine fish that reaches three inches in length. It is blue with a yellow tail.
In the Aquarium
Chrysiptera parasema is a hardy member of a saltwater aquarium. Because of this and its usually low price it is often recommended as a way for novice marine aquarium keepers to gain experience. Thirty gallons is typically quoted as the minimum tank size required to permanently house this fish.
It is less aggressive than most damselfish but will sometimes harass more passive fish. Despite its comparatively peaceful nature it can be territorial with members of its own species. This aggression can sometimes be reduced by keeping them in groups of three to seven. They do show schooling behavior when kept in large groups. Despite its hardy nature, it also must not be placed in an aquarium with larger predatory fish such as lionfish, and grouper which will often see it as a food source.
