My cory cat seems to have an open sore on the top of his head, right between his eyes. A couple weeks ago he had a white patch there, which I had treated with Melafix. It seems the sore is getting bigger, and today he won't eat and has just been laying in one spot. This morning I found him upside down in a plant, but he flipped over and swam to the bottom. Shoud I keep treating with Melafix, or does anyone have suggestions on something different?
I tried to take a picture but our digital will not focus for how close I need to get to actually see the sore.
