Freshwater aquarium sharks can give your fish tank added interest as these unusual looking fish typically create a lot of motion by swimming back and forth in bright schools. Before you introduce any fish into the tank, it is a good idea to do a little research to make sure that your environment is right for the fish and that he will get along with the fish you currently have.
Below is some information on freshwater aquarium sharks you might consider for your tank.
Bala Shark
These sharks are silvery with black tipped fins and tail. They are mild tempered and energetic. Buy several of them and you will have a fascinating school of fish gracefully swimming in your tank. They will do vest in a large aquarium with an exterior power filter. They require a water temperature between 78 and 82 degrees.
Rainbow Shark
These pale freshwater aquarium sharks have raspberry orange fins and tail. They are hardy but rather aggressive to other sharks but will do well with other fish. If you want to keep these sharks you should settle for only 1 fish per tank, or more than 6 as they can get a bit cranky with each other in small numbers. They like to have tubes to swim in and out of. They can grow to 9” and should be put in larger tanks with a water temp between 76 and 80.
Red Tail Shark
Has a gray body with a red tail and is aggressive to other sharks. Like the rainbow shark, these need to be kept alone or in schools of more than 6. They need a pipe, tube or cave to be happy and can grow to 5”. Optimum water temperature is between 76 and 80 degrees.
White Tip Shark Catfish
These fresh water aquarium sharks have a sleek shark body with a catfish head – kind of ugly if you ask me! They are very mellow fish that constantly vacuum the bottom for food. They can live in brackish, fresh or salt water. They like to hang out in a group and can grow pretty big so they are recommended for large tanks. Optimum water temp is between 78 and 82 degrees.
