Common name: Cheekspot wrasse

General information

The Yellow-axil Chromis, scientifically known as Halichoeres melasmapomus, is a captivating species of wrasse that is admired for its vibrant coloration and dynamic behavior. This species is part of the diverse and colorful wrasse family, Labridae, and is known for its distinctive yellow spot on the gill cover, which gives it its common name.

Care

Yellow-axil Chromis are moderately easy to care for, making them suitable for intermediate aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. These wrasses are active swimmers and require ample space to roam. A varied diet of meaty foods, such as mysis shrimp, brine shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

Like many wrasses, Halichoeres melasmapomus exhibits protogynous hermaphroditism, where individuals start life as females and can change to males if the social structure within their group requires it. In the aquarium, breeding is not commonly observed, but providing a stress-free environment with plenty of hiding spaces can encourage natural behaviors.

Habitat

The Yellow-axil Chromis is found in the Indo-Pacific region, from the Maldives to the Philippines, and north to southern Japan. They are typically associated with coral reefs, where they can be seen swimming in the water column or among the reef structure, at depths ranging from shallow waters to about 30 meters.

Their natural habitat includes a variety of reef settings, from lagoon reefs with rich coral growth to outer reef slopes with strong currents. In the aquarium, replicating aspects of this environment, such as water flow and rockwork, can help these wrasses feel at home.
