Pakistani Butterfly (Indian Ocean)

The glorious Pakistan, or Red Tail butterfly, appears to have been saturated in dark black ink. Towards its dorsal fin this dissipates into an intensely rich chocolate hue, and a contrasting dark stripe runs along the edges of its fins. Its caudal fin is bright scarlet red, and several stark white stripes run over its face. It grows up to 6.5 inches and needs an aquarium of at least 100 gallons. It is usually imported from the Indian Ocean.

This species is normally quite peaceful and, and should not be kept with aggressive tank mates. It can be quite aggressive towards its own species; if several are to be kept together they must be added at the same time to a large aquarium. Butterflyfish do not show differences between males and females. They are related to angelfish, but lack the angel's distinctive cheek spines.

A butterflyfish's favorite food is an anemone, so they should not be kept in the same aquarium with one unless it is guarded by aggressive clownfish. The butterflyfish knows to attack the anemone on its mouth, which does not sting, and will make a quick meal of it. Many species of butterfly also benefit from filamentous algae in the aquarium to graze on.

This species may nip on many types of corals, especially hard corals, clam mantles, sponges, and feather dusters. They do not typically bother other types of invertebrates such as crustaceans. They feel most secure when there is plenty of live rock to hide in, as well as open space for swimming. This species varies in its willingness to eat prepared foods, and should be offered a variety of meaty and herbivore preparations such as frozen Mysis shrimp, half shell clams, marine algae and Spirulina; it should be fed 2-3 times a day. Bloodworms or small live anemones may be used initially to entice it to feed. Soft food may also be pressed into the rock to provide grazing opportunities. Supplements such as Brightwell's Angelixer and Garlic Power may elicit a feeding response.
