Freshwater Sharks belong to the Cyprinidae family and are a favorite among many hobbyists. These fish are found primarily in Southeast Asia and Thailand, and get their name from their pointed head and large dorsal fin, resembling the saltwater shark in body shape. Resemblances aside, there are no other similarities between freshwater and saltwater sharks. These fish prefer aquariums that contain several hiding spaces, along with driftwood and larger thick leaved plants. Freshwater Sharks make a wonderful addition to the semi-aggressive aquarium, as they are very curious fish adding a great deal of personality and character.
