Description
The Dusky Kob, also known as Mulloway or Japanese Meagre, is a very large, predatory marine fish native to the Indo-Pacific. Popular as a game fish, it inhabits coastal waters and estuaries, feeding on smaller fish and crustaceans. Due to its immense size and predatory nature, it is not suitable for typical home aquariums and requires public aquarium-scale setups.
