Are there any sharks you can put in a 10 gallon tank?

There are no shark species that can live in a 10 gallon tank. Sharks require a large amount of space to swim and to find food, and even the smallest shark species require at least a 100 gallon tank. Additionally, sharks are predators that require a diet of live fish and other animals, and they cannot survive on the prepared foods that are typically fed to aquarium fish.
