Centropyge interrupta
A dwarf angelfish with an orange body scattered with blue-purple spots and a bright yellow tail. A temperate species from rocky reefs around Japan, it grows unusually large for its genus, to about 15 cm.
The Japanese pygmy angelfish (Centropyge interrupta) ranges along the Pacific coast of southern and central Japan and in the northwestern Hawaiian Islands (Midway and Kure) (FishBase), and is common around the Izu and Ogasawara islands. FishBase classes it as temperate: it lives in pairs on algae-covered rocky and coral reefs at 12-60 m. At up to 15 cm TL it is large for a Centropyge. The body is orange with blue-purple spots that become larger and more purple towards the tail, and the tail is bright yellow. The older spelling Centropyge interruptus is still widely used. Captive-bred fish are increasingly available, and it is worth asking what temperature a fish has been kept at before buying. It grazes rock surfaces, so an established tank with plenty of live rock suits it. It is scarce in the Japanese trade, and domestically bred fish are also sold.

The Japanese pygmy angelfish grows to Up to 15 cm TL.
The ideal temperature for the Japanese pygmy angelfish is 19〜24℃.
Wild-caught fish do best cooler than a typical tropical tank; Saltcorner suggests 19-24°C.

19〜24℃
Omnivore (algae, small invertebrates, sponges)
Wild fish prefer cooler water; Saltcorner suggests 19-24°C and specific gravity from 1.020. Avoid prolonged high temperatures in summer.
At least about 190 L (50 gallons), established, with plenty of live rock to graze. Not suited to small tanks.
Keep one Centropyge species per tank.
Underfed fish may nip clam mantles, anemones, LPS corals and soft corals such as zoanthids, so it is reef-safe only with caution.
It picks at algae and detritus. Offer spirulina-based foods and frozen brine shrimp and mysis several times a day, especially just after introduction.
It hides at first but becomes territorial once settled. When buying, ask what temperature it was kept at (wild-caught or captive-bred).
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Japanese pygmy angelfish is 19〜24℃. Avoid sudden temperature changes and maintain a stable environment.
Japanese pygmy angelfish typically reaches Up to 15 cm TL as an adult. Size may vary depending on care conditions and individual genetics.
Japanese pygmy angelfish feeds on: Omnivore (algae, small invertebrates, sponges). Aim for a balanced diet with appropriate feeding frequency.
