Okay so on friday i started to notice my 8inch dovii was swimming weird and laying on the bottom of the tank, he still eats and everything there is not sign of bloating he eats well and still has his aggression he swims out of his cave to chase off the 12inch buttakofri but he still swims weird i left for vacation on that friday so i couldnt do anything when i noticed it. When i got back today he was laying on the bottom and still swimming weird i put food in the tank and he came up to eat and was still aggressive but its like he struggles to stay swimming. I was thinking maybe its a swim bladder problem maybe a infection of some sort i was wondering if you guys could help ive had this happen with my female gt a few years ago and nothing i did helped her and she ended up dieing, i dont want to lose my dovii please help. here are the pics
