Common name: longbarbel goatfish

General information

The Longfin Goatfish, scientifically known as Parupeneus macronemus, is a distinctive species recognized by its elongated dorsal and pelvic fins. This tropical fish is part of the Mullidae family, which is known for the pair of sensory barbels located on the chin. These barbels are used to detect prey in the substrate. The Longfin Goatfish has a striking appearance with a white or pale body and a yellow stripe running along the side, which can make it a visually appealing addition to a marine aquarium.

Care

Longfin Goatfish require a spacious tank with a sandy bottom to mimic their natural habitat where they can use their barbels to forage for food. They are active swimmers and need plenty of open space. A varied diet consisting of small crustaceans, worms, and other meaty foods is essential for their well-being. They are generally peaceful but may compete with bottom-dwelling fish for food, so tankmates should be chosen with care.

Reproduction

In the wild, Longfin Goatfish are known to form large spawning aggregations, which is a behavior not commonly observed in home aquariums. Breeding them in captivity is challenging and not often attempted by hobbyists.

Habitat

Parupeneus macronemus is found in the Indo-Pacific region, from the Red Sea and East Africa to the Line, Marquesan, and Society Islands, north to southern Japan, and south to New Caledonia. They inhabit coral reefs and sandy areas adjacent to reefs, typically at depths ranging from shallow waters to about 30 meters.
