Care

Pink-Streaked Wrasses are relatively easy to care for but do require a stable and mature aquarium environment. They thrive in tanks with plenty of live rock for hiding and foraging. These wrasses are known to jump, so a tightly fitting lid or screen is necessary to prevent escape. They are carnivorous, feeding on small crustaceans and worms in the wild, so a varied diet of meaty foods is essential for their health in captivity.

Reproduction

In the wild, Pink-Streaked Wrasses are protogynous hermaphrodites, meaning they are born female and have the potential to change to male if the dominant male is removed. In the aquarium, breeding is rare, but environmental stability and a well-matched pair can increase the chances of successful spawning.

Habitat

Halichoeres binotopsis is found in the Western Pacific, from the Philippines to northern Australia. They typically inhabit shallow, coral-rich areas and rubble slopes, often seen darting among the corals and rocks in search of food.
