I need some input please. I have a male jag that is about 4 months/3.5". He is constantly swimming at an angle. Head about the 1 O'Clock position. Has been doing it since day one. This is my first jag so I blew it off as a trait or something but as he grows I'm worrying about swim bladder problems. He eats fine and acts normal besides being a wuss. He literally backs down to every fish in the tank. And hangs out in the back behind a rock in his angled position. Should I worry about this?
