Genicanthus

Genicanthus bellus

Randall, 1975

Ornate Angelfish, Bellus Angelfish, Bellus Lyretail Angelfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indian Ocean: Cocos-Keeling Islands; Western Pacific Ocean: Indonesia, Philippine, Marianas, Marshall, and Society Islands.

Size: 7 inches (17 cm)

Natural Environment: Inhabits deep fore-reef slopes and walls at depths of 150 to 300 feet (45 – 90 m) where currents are quite swift, and is an open water plankton feeder.

General Husbandry: This attractive species is rarely available in the trade because of its depth in the wild, yet when so, makes for a colorful and peaceful addition to both fish-only and reef aquariums. Its also among the prettiest angelfish with the male quite different in coloration than the female, i.e., sexually dimorphic. Females have horizontal white, black and blue body stripes that become vertical near the head. Male bodies are mostly grey and have a couple of horizontal yellow stripes separated by a tan area that runs the length of the body. Both have a tail that tapers into the body, resulting in what can be called a swallowtail appearance. In fact, those in this genus are sometimes called Swallowtail Angelfish.

Best maintained in moderately lit aquariums because they are collected in deep water, and those having excellent water flows and lots of wide-open swimming areas. As to diet, they should be offered at a minimum several daily feedings so as to quickly acclimate it to its surroundings. Like many others in this genus, their captive diet should consist of a wide variety of meaty foods including fortified brine shrimp, mysis and angelfish food preparations, and continued to be offered several times daily after its acclimated to its surroundings. Some flake foods, especially those containing Spirulina should also be offered occasionally, as algae, especially Spirulina is a healthy addition to all that consume it.

Depending upon its tankmates, it can be quite shy when first entering the aquarium, and may hide in caves and crevices. But as time passes, will become more outgoing. Those in this genus, as those in the genus Apolemichthys and Chaetodontoplus, are almost always very good tankmates and considered one of the least aggressive in the family. Keep in mind males will fight among themselves, so the limit is one per aquarium, whereas multiple females can be maintained, and all can be maintained with other genus angelfish.

Taxonomy:

    Order: Perciformes

    Suborder: Percoidei

    Family: Pomacanthidae

    Genus: Genicanthus

FYI: Keeping more than one genus of angelfishes in the same aquarium is possible, yet depends upon several aspects. The following suggested circumstances are just that, possibilities that when heeded and adjusted to actual aquarium conditions ‘may’ make multiple angelfish collections feasible.

Aquarium size – the larger the better.

Other species from the same genus should not be in the same aquarium.

The smallest and most docile genus species should be the first introduced with the largest and most malicious the last to be added.

Do not place similar coloration species in the same aquarium.

Those already in the aquarium should be well fed before adding a newcomer.

Have sufficient hiding places/rocky caves.

Keep in mind all angels have cheekspines at the edge of their gill cover; therefore use caution when handling and also avoid using a net to capture it, as it may become stuck or tangled in the net and become damaged when removed.
