Description
The Harlequin Fish, or Six-spot Rockcod, is a striking saltwater grouper known for its reddish-brown body adorned with numerous small blue or white spots and distinctive yellow blotches along its flanks. This predatory fish requires a large aquarium with ample hiding spots and robust tankmates, as it will consume smaller fish and crustaceans. It is a hardy species suitable for experienced intermediate aquarists.
