Description
The Rivulated Mutton Hamlet, also known as the Rivulated Grouper, is a large, predatory marine fish characterized by its distinctive wavy brown lines and spots on a lighter body. Found in the Indo-Pacific, it is a formidable hunter of smaller fish and crustaceans. Due to its significant adult size and predatory nature, it requires a very large aquarium and careful tankmate selection.
