Well, I was away for about 5 days, and my oscars were fed well before I left. Well it just so happens I had a pleco in the tank (about 3 inches long) die probally right as I left (I did not know this) I came back and seen it, so i scooped it out. Well its flesh literally peeled right off it's body, like it disinigrated. I looked at my oscars, and 3 of the 4 have very very very mild ick. My jack dehmpsy, GT, and the african chiclids are fine. All the fish are eating health and still very active. I did a water change immediately (literally about 85%) water temp is between 80-82 F. Is there anything else I should do?
BTW the water temp before the water change was like 70-72 I believe. It got pretty cold because my tank is right near my window and it's 20 degrees out side with 20 inches of snow
