I can't tell if he's being bitten or pinched or not. He's making the fast and erratic movements near the tank walls like he's trying to escape, but other times he'll just swim around and hang out for a few minutes. He swims back and forth under the heater sometimes too but I can't tell if he's doing it to scratch but when he does nothing comes off.
If it is ich how long do I have before he could kill my betta? And with the meds can I treat it with him still in the tank?
