When we think of underwater, we usually imagine various brightly colored creatures lying at the bottom of the ocean, right? Longnose butterflyfish is one such beautiful species that can be very attractive.

The longnose butterflyfish is a tropical marine animal adapted to living in, and near, coral reef areas, feeding on a variety of small invertebrates. It has a vibrant yellow body with an elongated snout that gives them a unique appearance. Other common names include yellow longnose butterflyfish, forceps butterflyfish, forceps fish, and long-nosed coralfish.

Long-nosed butterflyfish are among the most colorful and eye-catching patterned fish in the butterflyfish group, which may justify why they are so popular with aquarists. However, these butterflyfish require large tanks, about 75 gal (340.9 L) in size; this will give them plenty of open space to swim in. Moreover, there should be plenty of hiding spots in the aquarium, which can be created of corals and rocks, preferably live rock.

This fish will most likely ignore shrimp and crabs, but it may consume tubeworms and may attack urchins and starfish.

Would they make a good pet?

If you are impressed with its look and want to add it to your aquarium, remember this fish is not suitable for reef aquariums as they are harmful to the polyps of stony and soft coral species. One advantage of keeping it in a reef tank is that some individuals may help to rid the reef of irritating Aiptasia species such as the glass anemone (Aiptasia pulchella), though they are not as skilled at this as the raccoon butterflyfish (Chaetodon lunula) or the copperband butterfly. In general, it is a quiet fish and does well in fish-only aquariums. These butterflyfishes are typically kept single or as a pair in larger tanks. It does well with other non-aggressive fish, and it can also be placed in a somewhat aggressive population if introduced into the tank early. Smaller, non-aggressive fishes such as gobies, cardinalfish, fairy basslets, fairy, flasher wrasses, and tilefish are suitable tank mates. This species can also be kept with larger, more territorial angelfish. But it may not be recommended to be kept with other butterflyfish, as it is aggressive towards other members of its species as well as other butterflyfish of the same genus like longnose Atlantic butterflyfish, also known as Caribbean longnose butterflyfish.

Did you know...

This fish's color pattern and look are strikingly similar to its near relative, the big long-nosed butterflyfish (Forcipiger longirostris), also known as rare longnose butterflyfish. However, the snout of the big long-nosed butterflyfish is much longer than the F. flavissimus species.

Why is the longnose butterflyfish also known as forceps butterflyfish?

Its long nose is tipped with sharp jaws resembling a pair of needle-nose pliers. It can easily snip off the tentacles of tube worms, pick up copepods and mysid shrimp, and trace other tiny prey morsels hiding in cracks and crevices using this unique nose. Henceforth it is also known as the long-nose butterflyfish and the forceps butterflyfish.

What is unique about the longnose butterflyfish?

The yellow longnose butterflyfish is a beautiful fish to observe as it moves around the tank. Its bright yellow body is emphasized by a black face mask and a distinct eyespot at the tail. Their elongated snout, however, is its most distinguishing feature. Moreover, these fish can change color automatically based on their environment. The vibrant shades typically fade at night to blend in with the coral reefs, and when the fish feels threatened, the color becomes even more vibrant.
