Description
The Sevenfingered Threadfin is a large, predatory fish native to the Indo-West Pacific, often found in coastal marine waters and estuaries. It is characterized by its silvery body and distinctive free pectoral fin rays, which it uses to locate food on the substrate. This species requires a large aquarium with stable brackish or marine conditions and a diet rich in protein.
