Yellowtail Damsel Fish - Chrysiptera parasema - Yellow Tail Damselfish

Yellowtail Damsel Fish - Chrysiptera parasema: The Yellowtail Damsel is also known as the Yellowtail Blue Damselfish, the Yellowtail 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 Yellowtail 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 Yellowtail in a smaller tank if there aren’t many other inhabitants. Although Yellowtail 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 Yellowtail Damsel is particularly hardy and many hobbyists will use them to cycle a new tank. Using them to cycle ank 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.

Size: The Yellowtail Damshel grows up to 3 inches.

Minimum Tank Size: A single Yellow Tail Damsel Fish should have an aquarium of at least 20 gallons in volume. Yellow Tail Damsels do best when kept in temperatures between 72 and 78 degrees Fahrenheit (23 to 26 degrees Celsius), at pH values of 8.3 or 8.4. The specific gravity should fall between 1.020 and 1.025. When kept in a fish-only aquarium, Yellow Tail Damsels do well in a specific gravity between 1.020 and 1.023. However, if invertebrates are present in the aquarium, the range from 1.023 to 1.025 should be used. Yellowtail Damsel Fish are reef safe. They seem to get on well with other fish and invertebrates, although they may not always get along with other members of their species. Yellowtail Damsel Fish can be fed on flake food supplemented with lettuce or freeze-dried plankton.

Habitat: The Yellowtail Damsel comes from the central and western Pacific, including the Red Sea. The Yellowtail Damsels are found in Indian and Pacific ocean including areas of Srilanka, Mauritius and Australia.

Feeding and Diet: The Yellowtail Damsel is an omnivore. It will eat vegetable matter, spirulina, flake foods and mysis shrimp. The Yellowtail Damselfish will go after most fish food including vitamin enriched flake food, frozen, freeze dried and live foods The Yellowtail Damsel is also reef safe, as it will ignore invertebrates and feed on zooplankton and algae. The feedings should be made in small amounts several times per day.

Breeding: It has been reported that newborn Yellow Tail Damsels (Chromis xanthurus) often die within the first two to three days after hatching. It is theorized that this is because they won't eat rotifers. One possible method for feeding is to feed something smaller, such as paramecium, since these are smaller than rotifers.
