I recently added three bala sharks (3 inches each) to my 6x2x2 tank.
They have settled in quite well and have not bothered the other fish. Most of the time they school together in the mid to top level of the tank.
I've noticed since I added them that they like to swim to the top of the tank at the back where the outlet spray bars are, almost as if they like to swim against the current. Is this normal or is this a sign of lack of oxygen or another problem like ich in the tank? I don't have any powerheads in the tank so the only source of waterflow would be the canister outlet spray bars.
I've not kept bala sharks nor could I find this kind of info on them, so any guidance would be appreciated.
I'm hoping its not a serious issue here and just me being paranoid!
Thanks
