Select options Blackhawk Catfish (Wallagonia micropogon) $34.99 A recently described and massive growing catfish from the Mekong Basin in Southeast Asia, the Blackhawk Catfish is a large and distinctive predatory species. With its characteristic large mouth and eel-like body, this catfish makes for a unique display fish in a suitably large aquarium. They can be distinguished from their close relatives in the genus Wallago by their solid black dorsal and pectoral fins and distinctive black marbled pattern. Tankmates for this species should be chosen carefully as they will attempt to eat anything that can fit in their surprisingly large mouth. Due to their enormous adult size, this fish is recommended only for experienced hobbyists with the largest aquaria.
