Common name: Striped sweetlips

General information

The Blackspotted Sweetlips, scientifically known as Plectorhinchus lessonii, is a striking fish species admired for its distinctive pattern and behavior. Juveniles exhibit a dramatic coloration with black spots on a white body, which gradually changes to a more muted pattern with age. Adults have a silver-gray base with black spots scattered across the body and fins, and their thick lips are a notable feature.

This species is known for its 'grunting' sounds, produced by grinding their pharyngeal teeth, which can be heard during night dives. The sounds are used for communication and to deter predators.

Care

Blackspotted Sweetlips are a challenging species to keep in home aquariums due to their large adult size and specific dietary requirements. They require a spacious tank with plenty of hiding places and a peaceful environment. A varied diet of meaty foods such as shrimp, squid, and fish flesh is essential for their well-being.

Reproduction

In the wild, Plectorhinchus lessonii forms large aggregations during spawning. Little is known about their breeding habits in captivity, and successful breeding is rare in home aquariums.

Habitat

This species is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to New Caledonia. They inhabit coral reefs and lagoons, often found in areas with sandy substrates and reef overhangs, from shallow waters to depths of around 30 meters.
