Forcipiger longirostris
Forcipiger longirostris, commonly known as the longnose butterflyfish or big longnose butterflyfish, is a species of butterflyfish found on coral reefs throughout the tropical waters of the Indo-Pacific. Even with its distinctive, point-like long nose, the longnose butterflyfish still can easily be confused with its more common cousin F. flavissimus. Both species may be kept in aquariums.
Description
F. longirostris has a compressed yellow body with a black triangular region on its head, and as the name implies, a long, silvery snout. Usually 10 or 11 dorsal spines, a black spot on the anal fin, and rows of small black spots on the breast are found. The fish grows to about in length. In comparison, F. flavissimus has more dorsal spines, lacks the black spots, and its operculum is more curved.Rarely, F. longirostris can be found in an all-black form, as well, or the yellow portion may be brown.
