I had recentlymoved my ray from one tank to another. Moved with 2 other rays to a tank with rays already in it. All other rays were fine and eating well. I noticed yesterday the edge of disc was very light in color treated with melafix. Today I came home and thought she was dead when I went remove from tank found blood all over net and she took a breath I quickly saw blood was coming out of gills. I put her down because I thought it was the right thing to do. My question is what caused bleeding and should I do anything to protect others. Water is good nitrates at a constant 35ppm and was eating up to 3 days ago
Any help is appreciated
