Red Stripe Angelfish

Red Stripe Angelfish

The Red Stripe Angelfish (Centropyge eibli), better known as Eibl's angelfish, is a handsome, larger dwarf angel with a pale grey-tan body finely pinstriped in orange-red, a yellow-rimmed eye and a dark-edged tail. Hardy and full of character, it is one of the more popular Centropyge angels — and an interesting one, as juveniles are mimicked by a surgeonfish (Acanthurus tristis) that copies their colours for protection. It is a rewarding fish for the intermediate marine keeper.

Like other dwarf angels it has a bold streak and some appetite for picking at the reef, so a little caution is warranted in a coral system.

Natural Habitat & Origin

Centropyge eibli is found in the eastern Indian Ocean and adjacent western Pacific, where it lives among coral-rich rockwork, grazing algae and darting between crevices. It is a relatively bold dwarf angel that ranges over the reef as it forages.

In the aquarium it wants plenty of live rock with holes and crevices to claim as territory and shelter, with grazing surfaces of natural algae.

Care Requirements

Maintain stable marine conditions: salinity around 1.024–1.026, pH 8.1–8.4, and a temperature of about 24–26°C (75–79°F). Reaching about 15 cm (6 inches) — large for a dwarf angel — it is best given a tank of around 200 litres (about 55 US gallons) or more with abundant rockwork. A mature system with established algae greatly improves its acclimation and diet.

Diet & Feeding

The Red Stripe Angelfish is an omnivore that grazes algae in the wild along with associated microfauna. Provide a varied diet built around marine angelfish and herbivore preparations — including spirulina and marine algae — supplemented with frozen mysis and enriched blends. A tank with healthy algal growth on live rock offers valuable continuous grazing between feedings.

Behavior & Temperament

Centropyge eibli is semi-aggressive and territorial, bold for a dwarf angel and especially assertive toward other dwarf angels. Keep only one dwarf angel per tank unless the system is large, and add it after calmer fish are established. It spends its time working the rocks and defending its territory.

Tank Mates

Good companions are peaceful to semi-aggressive reef fish that occupy different niches — clownfish, gobies, blennies, wrasses, tangs and similar. Avoid other dwarf angels in smaller tanks. In a reef, treat it with caution: like most dwarf angels it may nip coral polyps, clam mantles or zoanthids, though a well-fed fish is less likely to sample corals.

Breeding

The Red Stripe Angelfish is a protogynous hermaphrodite and pelagic spawner. It has occasionally been bred in captivity, but rearing the larvae is demanding, so most trade specimens are wild-collected.

Common Health Issues

Centropyge eibli is hardy but, like all marine fish, can be affected by marine ich (Cryptocaryon irritans) and marine velvet (Amyloodinium ocellatum), particularly when stressed. Quarantine new arrivals, keep water quality stable, and provide plenty of grazing surface and cover. Mindful of its bold temperament and mild reef risk, it is otherwise a hardy, handsome and rewarding dwarf angel for a medium-to-large aquarium.
