He seems to be acting normally at this point, but still has some white spots on his head. It looks like some of it might be scarring, does ich leave scars? I also found a mushy ball of brown stuff at the bottom of his tank this afternoon, and I have no idea what it is. I'm sure it isn't an uneaten pellet, because I've been watching him pretty carefully, and it's about four times the size.
I'm not sure how much longer I should continue the medication, it doesn't specify how long I should treat. It's been a week since his first dose, and I don't know if continuing could harm him.
