Forcipiger longirostris also commonly referred as the Very-long-nose Butterflyfish resembles the Forcepsfish (Forcipiger flavissimus) but can be distinguished by its longer snout, smaller mouth gape, the number of dorsal fin spines (10-11 vs. 12-13 in the Forcepsfish) and by rows of small black spots on the breast. Forcipiger longirostris is widely distributed in Indo-Pacific from East Africa to the Hawaiian, Marquesan, and Pitcairn islands, north to the Ogasawara Islands, south to New Caledonia and Australia (Northern Great Barrier Reef); throughout Micronesia.
The Very-long-nose Butterflyfish is bright yellow; the upper half of head and nape is almost black, lower part of head and snout is silvery white, has a series of rows of blackish dots on chest; a black spot on anal fin just below base of caudal fin.
Forcipiger longirostris feeds mainly on whole organisms such as small crustaceans and is usually seen in pairs.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.
