In simple words, aquarium sharks are the species of fish that belong to the carp family Cyprinidae. These fishes are mostly found in freshwater and have torpedo-shaped bodies.
Generally, people get confused between freshwater aquarium sharks and saltwater sharks. So, to make things clear, saltwater sharks live in the ocean whereas freshwater sharks reside in rivers, lakes, and ponds.
Freshwater sharks are hard cartilaginous bony fishes of the class Osteichthyes. Unlike their ocean-dwelling cousins, freshwater sharks are not true sharks but are members of the carp family Cyprinidae.
U.S. Fishery Research Institute (FRI) has conducted research and concluded that there are around 19 shark species in the world that can be found in freshwater.
Out of these 19 species, only 3 to 4 species are commonly found in home aquariums. These include the Bala shark, Rainbow shark, Red-tailed black shark, and Whitefinned zebra shark.
Another rare finding in the study is that freshwater sharks can grow up to 2 feet long. For this reason, many people also call it monster fish. The average lifespan of a freshwater shark is around 15 years.
