Common name: yellowfin goatfish

General information

The Yellowfin Goatfish, scientifically known as Mulloidichthys vanicolensis, is a vibrant and active species popular among saltwater aquarium enthusiasts. This species is known for its striking coloration, with a silver to white body and a distinct yellow stripe running along the dorsal fin. The goatfish gets its name from the pair of chin barbels, resembling a goat's whiskers, which it uses to probe the sand for food.

Care

Yellowfin Goatfish are relatively hardy and can adapt to a variety of tank conditions, but they do best in larger aquariums that provide plenty of swimming space. They are active swimmers and will appreciate a sandy substrate that allows them to exhibit their natural foraging behavior. A varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the wild, Yellowfin Goatfish form large spawning aggregations, and their reproductive behavior can be quite spectacular. However, breeding them in captivity is challenging and not commonly achieved by hobbyists. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs.

Habitat

Mulloidichthys vanicolensis is found in tropical and subtropical waters of the Indo-Pacific region. They are commonly seen over sandy bottoms and coral reefs, often in schools, and can be found at depths ranging from shallow lagoons to about 110 meters. Their natural range extends from East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, and south to New Caledonia and the Austral Islands.
