Longnose Butterfly Fish

The Longnose Butterflyfish, *Forcipiger longirostris*, is a captivating and easily recognizable species, distinguished by its exceptionally long, forceps-like snout and vibrant yellow body. A striking black band runs vertically through the eye, and a small black spot is often present on the anal fin. This species is a popular choice for marine aquarists due to its active nature and unique appearance.

A minimum tank size of 70 gallons is recommended to provide ample swimming space and a stable environment. A well-established aquarium with plenty of live rock is essential, as the Longnose Butterflyfish will spend much of its time actively foraging for food within the rockwork. While generally considered reef-safe with caution, they may occasionally nip at certain corals, particularly soft corals and LPS (Large Polyp Stony) corals, as well as clam mantles. Therefore, they are best suited for a fish-only with live rock (FOWLR) aquarium or a carefully monitored reef tank.

In the wild, the Longnose Butterflyfish primarily feeds on small invertebrates found within crevices and cracks. In the aquarium, their diet should be varied and include a mix of high-quality marine flake and pellet foods, frozen mysis shrimp, brine shrimp, and other meaty foods. Offering live or frozen blackworms can also be beneficial. Due to their long snout, ensuring food reaches them can sometimes be a challenge, so target feeding may be necessary.

Longnose Butterflyfish are not typically bred in captivity. There are no readily apparent visual differences between males and females. They are generally peaceful towards other fish, but can be territorial towards conspecifics or other butterflyfish species, especially in smaller tanks. Introducing them as the last fish in the aquarium can help minimize aggression. They are a hardy species once acclimated and can be a rewarding addition to a suitable marine aquarium.
