My long nose butterfly died today. He was eating great.....even last night was eating very well. For 3 days he was showing signs of what I thought was ich (he been in my QT for 3 weeks now). He had a few small white dots but also some larger bumps that weren't white. Then he started showing damage to his body. I never saw him 'scratching' himself on any rock or anything. Here are some pics of him......anyone have any idea what this is? I have a couple other fish in the QT and want to know if I need to treat it or not. Thanks!
