Also known as the Black Fin Shark, the Columbian Shark is a catfish which will grow quite large in an aquarium. It may also be referred to as Jordan's Catfish or the West American Cat Shark. The Columbian Shark has a high fin and long "whiskers" that gives it a classic catfish appearance.Setting up a tank to match its natural environment will require plenty of plants and rocks. Since it grows quite large, starting with a minimum tank size of 70 gallons is recommended. As the Columbian Shark grows larger, there is a chance that the shark will eat smaller tank mates. This species prefers some aquarium salt in the water, and may also be acclimated slowly into a saltwater aquarium, as they live in both freshwater and saltwater during different times of their life.
