Hey guys.... ok so I have a betta question for you all.... I have one male betta in a 2.5 gallon tank. The tank is filtered, but has no heater because the temperature always stays right around 73-74 in my room. For about the past week, I noticed that he was having problems I guess balancing would be the right term? He like can't stay upright. Floating isn't an issue, so I don't think its his swim bladder. It's almost like his top fin is heavy and pulls him to that side, but then he'll try and straighten out and sway the other way. He ends up just kind of laying on his side on a plant leaf or floating up at the top. Any thoughts for this? I've had him since September and he looks to be full size, he was big when I got him though. Any thoughts would be much appreciated! Thanks!
