Description
The Swordspine Croaker (*Protonibea diacanthus*) is a large, predatory marine fish native to the Indo-West Pacific. Reaching nearly five feet in length, it is a formidable carnivore that preys on smaller fish and invertebrates. Due to its immense size and specialized needs, it is exclusively suited for expert care in very large public aquariums.
