The Yellowtail Damselfish

The Yellowtail Damselfish (Chrysiptera parasema ) is considered by many to be an ideal fish for the marine aquarium. Its extreme hardiness, beautiful colors, and even temperament all contribute to its desirability as a member of your saltwater aquarium.

The Yellowtail Damselfish is also known as the Yellowtail Blue Damselfish or the Yellowtail Demoiselle. With its dazzling blue body contrasted by a bright yellow tail, this fish will look stunning in any tank. The Yellowtail Damselfish is native to the lagoons and coral reefs of the Western Pacific. It will grow to a maximum length of three inches. The males are usually slightly longer and more slender than the females.

One of the things the aquarist appreciates most about the Yellowtail Damselfish is its compatibility with the other inhabitants of the tank. These Damselfish will generally not bother other fish, invertebrates, or coral. Although they may become aggressive towards their own kind, they usually do fine as a mated pair or in small, odd-numbered groups. They should share the tank with other peaceful fish.

The ideal tank for the Yellowtail Damselfish will have many small hiding places as well as a large open area. These fish are often shy and like to sleep in a protected spot. They are well suited for the reef tank. These fish can be kept in a smaller aquarium than many fish require, but it should be at least twenty gallons. The required water conditions are as follows: 72-78° F, sg 1.020-1.025, pH 8.1-8.4, dKH 8-12.

The Yellowtail Damselfish is not a picky eater; it will adapt to eating frozen as well as dried foods. A variety of foods should be offered including mysis and vitamin-enriched shrimp, crustacean flesh, and Nori. It will eat zooplankton and algae as well, and should be fed three times daily.

Yellowtail Damselfish have been known to spawn in captivity. The male will become aggressive toward the female when ready to mate. He may become very territorial after the eggs are deposited because he is responsible for their care and protection.

Yellowtail Damselfish are a great choice for beginner and experienced aquarists alike. Their striking good looks, easy care, and semi-aggressive nature all contribute to their value as saltwater aquarium fish.
