Keyhole Angel (Centropyge tibicin)
Max Size: 8 inches
Reef Compatible: With Caution. May eat soft polyps.
Minimum Tank Size: 70 gallons
The Tibicen Angelfish, also known as the Keyhole Angelfish or Melas Angelfish, is among the largest of the Centropyge genus, but has a dull blue to brownish-blue coloration, with a white vertical bar in the mid-central body area. The pelvic and lower portion of the anal fins are yellow.
A 70 gallon or larger tank with plenty of live rock for hiding and grazing is recommended for the Tibicen Angelfish, which may nip at stony and soft corals (sessile invertebrates) and clam mantles, and feed on filamentous algae and diatoms.
The Tibicen Angelfish is hermaphroditic, making breeding in an aquarium very difficult, and there are no distinguishable color differences between males and females.
To maintain a healthy Tibicen Angelfish, its diet should include Spirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items, with 2-3 feedings per day.
