Yellowtail Damselfish (Chrysiptera parasema)
The Yellowtail Damselfish is extremely hardy and gorgeously colored. In fact, Chrysiptera parasema is considered by many aquarists, both beginning and advanced, to be the ultimate damselfish. This is partly because its jewel-blue body is contrasted by an energizing yellow tail. This color combination looks stunning against any backdrop of corals and live rock. But what pleases aquarists most is that the Yellowtail Damsel is less aggressive and does not need as large of an aquarium as other Damsels. Scientific Name : Chrysiptera parasema Common Names : Blue Yellowtail Damselfish, Goldtail Demoiselle Yellowtailed Blue Damsel Care Level : Easy, good for saltwater beginners, but don't use them to cycle your tank. This is not needed with the use of live rock as the primary biological filter. Life span : 4 - 6 years, possibly longer Size : Up to 3 inches (8 cm) pH : 8.1 - 8.4 Temperature : 75°F - 80°F (24°C - 27°C) Specific Gravity : 1.020 - 1.025 Carbonate Hardness (dKH) : 8 - 12° Origin / Habitat : Indo-Pacific Temperament / Behavior : Much like other damsels, this one can be moderately aggressive. Aggression can be lessened or spread out if you have 3 to 7 in your aquarium. Breeding / Mating / Reproduction : Tank Size : 30 gallon minimum Compatible Tank Mates : Avoid keeping them in an aquarium with Lionfish, Snappers, Groupers, Triggers, Eels or any other predatory fish large enough to eat them. Reef Tank Compatible? : They shouldn't bother the corals and/or anemones but can sometimes be little jerks to the other fish in a reef aquarium setup. Fish Disease : Saltwater Fish Disease - Diagnose, Symptoms and Treatment Diet / Fish Food : Omnivore - try to give them a variety of foods. They will take vitamin enriched flake foods, frozen and definitely live foods. Tank Region : Middle to bottom Gender : Difficult to determine
