I've had my fish looking like this for 4 weeks now, he lives with a bgk in a 220ltr. Temp is 24 I got told to raise it from 22 that it was on. I got some treatment and I asked if it would harm the knife and it certainly has he's really weak but still moving about the tank.. even though he looks drunk. I've only treated it twice the fire mouth is seems to be improving but they're still there. Any advice would be amazing
