I am wondering because i was out of town for almost 2 weeks and the water change my cousin promised to do didnt happen. now my pikes eyes are cloudy and it looks like he has HITH. I have been treating him with 20% water changes, and a vitamin c supplement and he seems to be coming around eyes clearing up feeding much better and no new spots on his head in fact the old ones seem to be healing up. Is there anything else i can do besides my cousin.
