Blackspotted Rubberlip

(Plectorhinchus gaterinus)

Plectorhinchus Sweetlips should only be added to very large aquariums preferrably zoo's and public aquariums as they grow very large very quickly. Provide the Plectorhinchus Sweetlips an aquarium with ample open swim area, plenty of rockwork with caves, crevices, and cracks to hide and rest in. Juveniles are very colorful, as they mature their color begins to fade. Sweetlips grind their teeth and the sound resonates in their swim bladder making a Gruntsing noice. Sweetlips are peaceful, shy, nocturnal bottom feeders. Provide a diet rich in meaty foods fed several times daily. They will consume small fish and crustaceans. If they are not eating try fortified live Brine, Glass/Grass shrimp or Black Worms.

Blackspotted Sweetlips are also sometimes known as the Blackspotted Rubberlip. Rarely seen in the aquarium trade. Juvenile and adult Blackspotted Sweetlips may have drastic color differences. Juveniles have horizontal black and white stripes while adults will have an overall silver body, yellow belly, gray to blue head and yellow fins with black spots. The Blackspotted Sweetlips can grow to a little over 17".

We recommend a minimum aquarium size of 250 gallons or larger for this species.
