Common name: spinster wrasse

General information

The Yellowhead Wrasse, scientifically known as Halichoeres nicholsi, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. This species is part of the Labridae family, which is known for its hardy and beneficial members in the reef aquarium community. The Yellowhead Wrasse is distinguished by its striking coloration, with a bright yellow head that transitions to a blue-green body, and a series of vertical red stripes towards the tail.

Care

Yellowhead Wrasses are relatively easy to care for, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and hunting. These wrasses are known for their voracious appetite for small invertebrates, so they may not be suitable for tanks with small shrimp or crabs. A varied diet of meaty foods, such as frozen mysis shrimp and brine shrimp, will keep them healthy and vibrant.

Reproduction

In the wild, Yellowhead Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is absent. In the aquarium, breeding is less common, but with a group consisting of one male and several females, spawning may occur. The male performs an elaborate courtship dance to entice the females to release eggs, which are then fertilized in the water column.

Habitat

Halichoeres nicholsi is native to the Western Atlantic, ranging from Florida and the Gulf of Mexico to the northern coast of South America. They are typically found in shallow reefs and seagrass beds, where they can be seen darting among the cover in search of food.
