I have a 75G tank, when I got back from my classes today I noticed my Bala Shark swimming on it's side. I don't think it's dying because it does swim, but it seems to drift around the tank with the current. I was doing a bit of research and I think there is a problem with it's swim bladder. Could this be the case? Or do you think my Shark is dying? I did a 30% water change and water tested as follows:
Water readings: pH - 7
NO3 - 7
NH3 - 0
NO2 - 0
