Native to Southeast Asia, these freshwater tropical sharks are not really the sharks we see in Jaws or in Finding Nemo! They generally come from the rivers and streams of Thailand and these “shark-like” fish, are known for their sleek, torpedo-shaped bodies and active swimming patterns. These fish can be mildly territorial and require ample swimming space and hiding spots. They are fun to watch in a community aquarium and add a dynamic presence with their fast swimming behaviour.
