If you are referring to bala sharks, your sharks will get to 12 to 14" in size. Your going to need a much larger tank for them in the near future.

these fish need ALOT of swimming space. a 30g just won't be good for the longterm health of balas.

What other fish do you have with them at the moment and is the tank matured (cycled) ?

[Lady Hobbs]

At this point, doesn't matter what you have. Those fish need to be returned and can never make it in a 30 gallon.

It should also be mentioned that balas should be kept in schools. Yet another reason why they are unsuitable for your tank.
