Centropyge eibli
The Eibli Angelfish, also known as the Blacktail Pygmy Angelfish, is a hardy and visually distinctive dwarf angelfish admired for its earthy coloration and bold contrast. Its adaptability and resilience make it one of the more approachable dwarf angelfish for hobbyists seeking personality and movement without extreme care demands. Eibli Angelfish reaches an adult size of approximately 4–5 inches, making it slightly larger than some other Centropyge species. Its body displays a tan to brownish base color with fine horizontal striping, accented by a pale face and a distinct black caudal (tail) fin, which gives the fish its common name. Subtle blue edging along the fins becomes more noticeable under reef lighting, adding understated elegance rather than flashy coloration.
Eibli Angelfish thrives in aquariums of 70 gallons or larger with a mature aquascape rich in live rock, caves, and overhangs that allow for natural grazing and territorial boundaries. It should be housed with peaceful to moderately assertive tank mates and kept singly to minimize aggression toward similar species. Reef systems should provide ample rockwork and grazing opportunities to discourage coral nipping, as this species is reef safe with caution. Stable water conditions, open swimming areas balanced with shelter, and a structured reef layout help promote confident behavior and long-term success.
In the wild, Eibli Angelfish feeds on algae, detritus, sponges, and small invertebrates, classifying it as an omnivore. In captivity, it adapts well to a varied diet that includes spirulina-based foods, marine algae, frozen mysis shrimp, enriched brine shrimp, and high-quality angelfish preparations with sponge content. Regular, varied feeding supports coloration, immune health, and reduces the likelihood of coral nipping.
