Description


General: Also known as the Tibicen or Melas Angel, the Keyhole Angel is one of the largest members in the Centropyge genus reaching just under 8 inches in the home aquarium.

Diet: Offer a diet of frozen shrimps, angel specific frozen foods, herbivorous foods (ex: Spirulina, sheet algae), a high quality marine flake, and other frozen options for optimal health, color, and longevity.

Compatibility: The Keyhole Angel can be kept with a variety of passive to semi-aggressive fish and is best kept as the only Centropyge angelfish in a system, unless all intended dwarf angels are introduced into a system at once. Keep in mind that the system should well exceed in resources and space if accommodating multiple Centropyge species. This gives the best outcome of a Keyhole Angel coexisting with others in the genus. The Centropyge genus includes some of the most compatible angelfish for a reef system. Take caution however, an especially underfed, under nourished, or crammed individual may nip at coral. The Keyhole Angel will consume nuisance filamentous algae and diatoms off of liverock and other surfaces.

Environment: The Keyhole Angel should be added to an established system that has completed the nitrogen cycle. Fish are sensitive to temperature change; maintaining a stable temperature is important for the overall health of any fish. At full size, it should be housed in no less than 75 gallons with an abundance of liverock to graze on and retreat to if necessary. The Keyhole Angel is shy upon initial introduction, but will become bolder in personality as it adjusts.

Sexual Dimorphism: Difficult to distinguish male from female. Females will generally be black in color, while males may appear to have more of a dark blue hue to them.
