My rainbows seem to have something going on, and it looks like its getting worse. They have all been in my community tank for some time now, and I have not noticed any other problems with any other fish. My small rainbow was the first to show signs. He has a fleshy sore around his left fin and up around his head. At first I thought these were just battle wounds from the 2 others that are quite bigger. Now I am starting to see marks on my other rainbows. They do chase each other around quite a bit, so not sure if this is from fighting, or something worse.
