just askin, i know this might be dumb, but I have seen several silvers on mfk young and small, but I have never kept one up until about a month ago. First of all I think he is awsome. Great appetite and color, but does anybodies have a peacock like spot on the gill area? Is that normal?...Water,PH and everything is fine. He had it when I got him. It is just a multicolored spot on the gill area. Anyone?
