Care

Provide plenty of rockwork and rubble with hiding places. The minimum tank size of about 200 litres is our own estimate from the adult size and habits, not a figure from the sources. No species-specific water figures are given in the sources, so the values here are general marine aquarium guidance rather than figures for this fish: 24–27 °C, pH 8.1–8.4 and a specific gravity of 1.023–1.026. Keep conditions stable, with low nitrate and good oxygenation. Little is recorded about its behaviour; like other pygmy angels it stays close to cover. Deep blue body with an orange-yellow head and back. Very similar to the African flameback (Centropyge acanthops), which has a clear rather than blue tail. Popular; thousands were exported from Brazil. The article gives no IUCN category.

Diet

Eats algae and sponges. Provide live rock to graze and offer frozen mysis, enriched brine shrimp, angelfish foods with sponge, and marine algae two or three times a day.

Breeding

Marine angelfish are pelagic broadcast spawners: a pair rises into the water column, usually around dusk, and releases eggs and sperm together. Lays floating eggs with drifting larvae. Not routinely bred in home aquaria.

Compatibility and tank mates

Listed as reef safe with caution. Dwarf angelfish graze live rock and may nip large-polyp stony corals, zoanthids and clam mantles, especially when underfed. Keep one per tank (or one male with females in a large system) and avoid other Centropyge unless the tank is big and well furnished. Generally fine with clownfish, gobies, wrasses and tangs.
