The Eibli Angelfish is widely referred as the Blacktail Angelfish, Red Stripe Angelfish, Eibl's Pygmy Angelfish, Blacktail Angelfish and the Orangeline Angelfish. It should be provided with plenty of hiding places, so that it feels comfortable in the tank. The Eibli Angelfish has a brilliant sapphire-blue stripe outlining the caudal fin that makes it a captivating fish in the tank. It should be added in the tank not less than 30 gallon or larger aquarium with large amounts of live rock for hiding and grazing. The Eibli Angelfish prefers not to be housed with other Dwarf Angels and other predatory fishes. Since it may occasionally nip at sessile invertebrates and clam mantles, the Eibli Angelfish is considered reef safe but with caution. It is extremely difficult to breed the Eibli Angelfish in an aquarium, since there are no distinguishing characteristics that help to differentiate the males from females. The Eibli Angelfish should be given a diet that may include Spirulina, marine algae, mysis or frozen shrimp, and other meaty items. It thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4. Although some fishes are tolerant of lower levels of Nitrate, and make sure to keep Nitrate as close to zero as possible, and certainly under 20ppm in the tank.
