The term “freshwater shark” refers to sharks that have adapted to life in freshwater settings like rivers and lakes. The Iridescent Shark, Bala Shark, and Rainbow Shark are just a few examples of well-known freshwater sharks.
Since freshwater sharks are so visually appealing and have such a dynamic swimming pattern, they are in high demand by the aquarium trade. Since they are hardy and require little care, they are frequently seen in big community aquariums.
As a member of the cyprinid subfamily of fish, the freshwater shark shares a closer evolutionary relationship with carp and minnows than it does with other sharks. Several different types of freshwater sharks exist, and the largest of them can reach impressive lengths.
If you do your homework on the species you’re interested in and give them the right environment and care, freshwater sharks, in general, can be wonderful additions to a home aquarium.
