Common name: Redlined wrasse

General information

The Twospot Wrasse, scientifically known as Halichoeres biocellatus, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. Its body is elongated with a mix of green, yellow, and red hues, and as its common name suggests, it features two distinctive black spots on the dorsal fin. This species is part of the Labridae family, which is known for its members' intricate color patterns and important role in maintaining reef health by controlling populations of smaller invertebrates.

Care

Twospot Wrasses are relatively hardy and can adapt to life in captivity if provided with a well-structured environment that mimics their natural habitat. They require a tank with plenty of live rock for hiding and foraging, as well as a sandy substrate where they can burrow at night or when feeling threatened. These wrasses are known to jump, so a secure lid is essential to prevent escape. They thrive on a varied diet that includes small crustaceans, mollusks, and marine-based flake or frozen foods.

Reproduction

In the wild, Twospot Wrasses are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. This usually occurs when there is an absence of a dominant male in the group. In the aquarium, breeding these fish can be challenging due to their complex social structures and reproductive behaviors.

Habitat

Halichoeres biocellatus is native to the Indo-Pacific region, where it is commonly found in shallow, coral-rich areas and lagoons. They prefer environments with abundant coral and rocky outcrops that provide both food sources and shelter. In the aquarium, replicating this environment will help ensure the well-being of the Twospot Wrasse.
