Appearance
The Bluestriped Angelfish displays a striking dark blue to black body with bright yellow or white vertical stripes running along its flanks. It has a compressed, disc-like body shape typical of pomacanthid angelfish, and adults develop a characteristic rounded dorsal and anal fin profile.
Origin
Indo-Pacific region, from the Philippines and Indonesia westward through the Indian Ocean to the Red Sea and East Africa, with populations also recorded from Sri Lanka and the Andaman Sea.
Diet Details
In the wild, Bluestriped Angelfish feed on sponges, tunicates, and small crustaceans. In captivity, they are notoriously picky eaters; offer a varied diet of high-quality sponge-based pellets, frozen mysis shrimp, enriched Artemia, and live rock with natural fauna. Frequent small feedings often succeed better than larger meals.
Difficulty Level
This species is challenging for most hobbyists due to its specific dietary and water-quality requirements, reluctance to feed in captivity, and susceptibility to parasitic diseases. Only experienced aquarists with well-established systems should attempt captive care.
Diet
omnivore
