Common name: Wrasse

Pseudocheilinus is a genus of wrasses known for their vibrant colors and dynamic behavior. Popular in the reefkeeping hobby, these small to medium-sized fish are appreciated for their pest control abilities, as they often feed on bristle worms and other small invertebrates. They are generally peaceful but can be territorial, especially towards conspecifics. Providing a well-structured environment with plenty of hiding places and a sandy substrate is essential for their well-being. They are protogynous hermaphrodites, with the ability to change sex from female to male under certain social conditions.
