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.
Native to the reefs of the Indo-Pacific, this member of the Pomacentridae family prefers multiple hiding places and peaceful tankmates. Though most Yellowtail Damselfish will ignore other fish, invertebrates, or corals, some may be territorial towards its own kind or similar-sized fish. The Yellowtail Damsel is best kept in small groups of odd numbered fish in suitably sized systems.
Also known as the Yellowtail Blue Damselfish or Yellowtail Demoiselle, and sometimes confused with the Azure Damselfish, C. parasema feeds on zooplankton and algae in the aquarium. For best care, it should also be fed a varied diet of meaty foods, such as mysis and vitamin-enriched shrimp. It is best to feed several small meals throughout the day.
Yellowtail Damsels have been bred in captivity. Though difficult to sex, males are usually larger and more slender and become aggressive towards females when ready to mate. However, the male Yellowtail Damsel is ultimately responsible for the care and guardianship of the eggs and will become very territorial while watching over his brood.
Seachem Reef Reactor Lg
Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 - 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.
Rinse Reef Reactor™ prior to initial placement in your calcium reactor. The rate of water flow through the reactor in conjunction with the pH of the water inside the reactor will control the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor and adjust the rates of water flow and CO2 injection to attain the desired concentrations of calcium and alkalinity in the effluent.
Use Seachem’s Reef Status™: Magnesium and Reef Status™: Calcium test kits to measure alkalinity, calcium, and magnesium concentrations.
