Common name: Pink-snout wrasse

General information

The Yellow-axil Wrasse, Halichoeres kallochroma, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. Known for its striking yellow axil spot where the pectoral fins meet the body, this wrasse is a favorite among hobbyists. As a member of the family Labridae, it exhibits the typical wrasse behavior of being both curious and somewhat territorial.

Care

Yellow-axil Wrasses are relatively hardy and can adapt to a variety of aquarium conditions. They require a tank with plenty of live rock for hiding and foraging. A sandy substrate is also beneficial as these wrasses may bury themselves in the sand when they feel threatened or during the night. They are not picky eaters and will accept a wide range of foods including frozen, live, and flake foods.

Reproduction

In the wild, Halichoeres kallochroma is known to be a protogynous hermaphrodite, meaning individuals start life as females and can change to males as they mature. In the aquarium, breeding these wrasses can be challenging due to their complex social structures and the need for precise environmental conditions.

Habitat

The Yellow-axil Wrasse is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to the Ryukyu Islands. They typically inhabit coral-rich areas of lagoons and seaward reefs, usually at depths of 1 to 30 meters. In the aquarium, replicating their natural environment with a mix of coral and open swimming space is ideal for their well-being.
