Double Saddle Butterfly (Asia Pacific)

The alluring Double Saddle, or False Falcula butterfly, has two wide black stripes draped over its back which dissipate into fine stripes as they reach its belly. It is primarily pure white, except for its rear end which is deep dandelion yellow, and the lemony tips of its dorsal fin. A dark mask covers its eyes and it has a long snout. It resembles the True Falcula butterfly but has less yellow on its dorsal fin. It grows up to 6 inches and needs an aquarium of at least 100 gallons. It is regularly imported from Bali.

This species is normally quite peaceful towards all other fish, including other butterflyfish, and should not be kept with aggressive tank mates. It can be kept in pairs which should 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, 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 is hardy and usually easy to feed on 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.
