Big Longnose Butterflyfish

The Big Longnose Butterflyfish, scientifically known as Forcipiger longirostris, is a marine fish species belonging to the family Chaetodontidae. This species is named after its long, pointed snout, which it uses to search for food among crevices and rocky areas. They can grow up to 10 inches (25 cm) in length, but their average size in captivity is usually around 6 inches (15 cm).  The Big Longnose Butterflyfish is popular among saltwater aquarium enthusiasts due to its unique appearance and behavior. They are relatively peaceful and can be kept with other non-aggressive fish species. However, they should be kept in a tank with plenty of hiding spots and space to swim around.

In the wild, the Big Longnose Butterflyfish feeds on a diet of small crustaceans, plankton, and benthic invertebrates. In captivity, they should be fed a varied diet consisting of frozen or live foods such as brine shrimp, mysis shrimp, and chopped seafood. They can also be fed high-quality commercial flake and pellet foods designed for butterflyfish species.

There are no visible differences between male and female Big Longnose Butterflyfish.

Breeding the Big Longnose Butterflyfish in captivity is extremely challenging and rarely successful. They are known to spawn in pairs, but the larvae are very difficult to raise to adulthood.

The Big Longnose Butterflyfish is susceptible to common saltwater fish diseases such as ich and velvet. Proper quarantine and acclimation procedures are essential when introducing new fish to the aquarium to prevent the spread of disease.

The Big Longnose Butterflyfish is found in the Indo-Pacific region, including the Red Sea and the coast of East Africa to the Hawaiian Islands, and as far north as southern Japan and as far south as the Great Barrier Reef.

The Big Longnose Butterflyfish is not aggressive towards other fish, but they are known to nip at corals and invertebrates. Therefore, they should be kept in a reef aquarium with caution.

Proper acclimation is crucial for the health of the Big Longnose Butterflyfish. They should be slowly acclimated to their new environment by gradually adding small amounts of water from the aquarium to their transport bag over a period of at least an hour before releasing them into the aquarium.
