Description
The Pacific Threadfin is a large, schooling marine fish known for its distinctive thread-like pectoral fin rays. Found in coastal waters of the Indo-Pacific, it is a popular food fish and requires an extremely large aquarium due to its potential adult size. They are active predators, feeding on crustaceans and smaller fish.
