I have some Bala Sharks, good size ones too. One of which is a good 7 or 8 inches. They are at the point where I can no longer safely keep 'em. So I think I'm gonna have to take 'em to a pet store. The trip is about 30 minutes one way. Knowing this what is the best way to transport them, should I fill up a 10 gallon up with some water from their aquarium their in now? What about air?
