Appearance

A small, disc-shaped angelfish with a predominantly yellow body and three distinctive dark blue-black spots: one on the head, one on the upper body, and one on the rear dorsal region. The fish has a rounded profile typical of pomacanthids, with pointed dorsal and anal fins. Adult coloration is bright and contrasts sharply with the dark markings.

Diet and feeding

Feed a varied diet of high-quality angelfish pellets, frozen mysis shrimp, and blanched vegetable matter (spinach, nori). Offer food 2–3 times daily in smaller portions. Supplement occasionally with meaty foods to ensure adequate nutrition and coloration.

Difficulty and care for the Three-Spot Angelfish

The Three-Spot Angelfish is moderately difficult, requiring stable water conditions, a minimum 75-gallon tank, and careful tank-mate selection. While hardier than many angelfish species, it can be territorial and may nip at soft corals and clam mantles in established reef systems.

Common health issues

Ich (white spot disease), marine velvet, head-and-lateral-line erosion (HLLE), fin rot

Origin and habitat

Indo-Pacific region, ranging from the Red Sea and East Africa through the Indian Ocean to the central Pacific, including Indonesia, Philippines, and Micronesia.
