Flagfin Angelfish

A sponge-eating species that is difficult to keep in aquariums. Scott W. Michael

[edit] Overview

This beautiful fish usually fares poorly in the home aquarium. Chances of keeping it successfully are increased in a reef-type system with plenty of invertebrate-encrusted live rock. Younger specimens tend to acclimate better, and individuals from areas other than the Philippines tend to have greater rates of survival.

Family: Pomacanthidae

Other common name(s):

  • Threespot Angelfish

Native range:

Habitat: Coral reefs. Provide a well-established aquascape with caves and bolt holes for hiding.

Maximum length: 25 cm (10 in)

Minimum aquarium size: 284 L (75 gal)

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

General swimming level: All levels.

[edit] Feeding

Difficult to feed. This a sponge- and tunicate-eater that often fails to adapt to aquarium fare. Try feeding it sponge-containing frozen angelfish rations, vitamin-enriched brine shrimp, and mysid shrimp as well as plentiful plant material, including frozen preparations for herbivores and marine algae.

Feed at least 3 times a day.

[edit] Aquarium Compatibility

It is usually not overly aggressive toward unrelated species, but may fight with close relatives. Only one should be housed per tank.

Not recommended for the reef aquarium. May nip at sessile invertebrates, including stony and soft corals, and clam mantles.

[edit] Special Care

Can be quite shy at first and should have a choice of good hiding places.

[edit] Breeding/Propagation

Not recorded in captivity. Pelagic eggs and larvae.
