Pyramid Butterfly - Yellow (Asia Pacific)

The spectacular Yellow Pyramid butterfly is a highly sought after gem. Intense lemon yellow coloration is eclipsed by a triangular blotch as white as pure snow. Its face is a contrasting dark chocolate to black. It grows up to 7 inches and needs an aquarium of at least 125 gallons. It is quite rare, unlike the similar Black Pyramid butterfly which is more commonly available.

This species is hardy and normally quite peaceful; if it is added first it may be kept with aggressive tank mates. It can be kept singly or in pairs or groups 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 is a planktivore and is considered one of the most reef safe butterflyfishes. However, caution should be used when combining it with corals, clams, 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 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.
