Choosing a Shark

As you window shop the fish in your aquarium shop, you may be struck by a few called “sharks.” While not in any way related to the type of predator made famous by the movie “Jaws,” they do have large fins and shark-like movements. They can also grow large, become aggressive in the tank – and even jump out.

While these are attractive, generally hardy fish, easy to care for and interesting to watch, only a couple of species make for good fish in the community aquarium. The smallest of them will grow to around 5 inches, the largest to nearly 2 feet. They are fast swimmers and need room to move. Most do not do well with others of their kind, either.

Types of Tank Sharks

Beware: These sharks are exceptional jumpers and have no problem launching themselves 2 feet above the tank. Make certain that the tank cover actually covers the entire tank, and use caution when making water changes or you may find your shark on the floor.
