Common name: Whiteface waspfish

General information

The White-Breasted Wrasse, scientifically known as Richardsonichthys leucogaster, is a small and colorful marine fish that is a member of the wrasse family, Labridae. This species is known for its distinctive white underbelly and the striking patterns that adorn its body. The White-Breasted Wrasse is not as common in the aquarium trade as some other wrasses, but it can make a captivating addition to a reef or fish-only aquarium due to its vibrant colors and active behavior.

Care

White-Breasted Wrasses are relatively hardy and can adapt to life in captivity if provided with a well-established aquarium that mimics their natural environment. They require a tank with plenty of live rock for hiding and foraging, as well as a sandy substrate where they can burrow. These wrasses are known to jump, so a tightly fitting lid or screen is necessary 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, Richardsonichthys leucogaster exhibits protogynous hermaphroditism, where 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 reproductive behaviors. Hobbyists aiming to breed them should provide a stress-free environment with multiple hiding places to encourage natural behavior.

Habitat

The White-Breasted Wrasse is found in the Indo-Pacific region, particularly around coral reefs and rocky substrates. They are typically seen at depths ranging from shallow waters to about 30 meters. Their natural habitat includes areas with abundant coral growth and clear waters, where they can easily hunt for food and evade predators.
