My sister's had a betta that has a tumor for a little bit now, probably around 3 weeks to a month. I was just wondering when we should really start to worry about putting him down. I know what behavioral signs to look out for, but I want to know any physical signs.
Courage's tumor is right above his right eye and has grown quite large, which has effected the eye. It only points downward now and we aren't sure if he can see out of it or not. The tumor itself has slowly started to turn white as it's grown but really hasn't affected his behavior. He's still spunky and building bubble nests.
We change his water a little more frequently than a 2.5 gallon needs because if we don't his water smells like sulfur. We also experimented with dosing his tank with tetracycline, which seemed to make him feel a bit better.
I know a few members have had bettas with tumors on here and was just wondering when you guys decided that it was time based on looks or if you have any experiences that might help him get a little bit of relief.
I'll try to post the best picture I can get tomorrow.
