Asfur angelfish

This species is native to the Red Sea and the Western Indian Ocean, extending along the East African coast to the Gulf of Aden and the Persian Gulf. It primarily inhabits silty coastal coral reefs rich in soft corals and sheltered outer reef slopes at depths between 3 and 30 meters, preferring areas with plenty of caves.

Belonging to the family Pomacanthidae, it features a tall, oval-shaped, and laterally compressed body. Adults can reach a maximum length of approximately 40 centimeters. It possesses a prominent spine on the preopercle, characteristic of all angelfish. The dorsal and anal fins develop long, flowing filaments as the fish matures.

It is a solitary and territorial species. In the wild, it defends large territories on the reef. In captivity, it displays aggressive behavior toward other angelfish, especially those with similar color patterns or sizes, while remaining relatively tolerant of unrelated fish species if given enough space.

The adult coloration is magnificent, featuring a deep blue-purple body highlighted by a vibrant vertical yellow crescent on the flank. The caudal fin is entirely bright yellow. Juveniles look completely different, displaying a black body with vertical blue and white stripes. No visible external sexual dimorphism is present.

Requires a very large aquarium of at least 600 liters for an adult specimen. The layout should feature robust live rock structures arranged to create large caves, archways, and secure hiding places, which are crucial for reducing stress, while still leaving ample open swimming space.

An omnivorous feeder that specializes in consuming sponges and tunicates in the wild. In the aquarium, it must be offered specialized angelfish preparations containing sponge material, along with dried nori, spirulina, frozen foods like mysis, brine shrimp, and krill. Feed multiple times a day.

Demands stable water parameters and excellent filtration: temperature between 24°C and 27°C, pH range from 8.1 to 8.4, specific gravity of 1.020 to 1.025, and KH between 8 and 12 dKH. Ammonia and nitrites must be kept at zero, with nitrate levels kept low (under 20 ppm) to prevent health issues.

Not entirely safe for reef aquariums containing corals. It will likely nip at soft corals, zoanthids, LPS corals, and clam mantles. It coexists well with other active fish like tangs, wrasses, anthias, and clownfish. Avoid housing with other large angelfish, especially from the Pomacanthus genus.

Captive breeding in home aquariums has not been successfully documented. In nature, they are pelagic spawners, pairing at dusk to release gametes into the water column. Raising the larvae is extremely difficult due to their microscopic size and specific initial planktonic food requirements.

Susceptible to common marine skin parasites like Cryptocaryon irritans and Oodinium, as well as Head and Lateral Line Erosion (HLLE) if exposed to poor water conditions or nutritional deficiencies. A strict quarantine protocol and vitamin-enriched foods are highly recommended.
