I'v been talking to some people about this but I'v noticed that on one of my neons the red stripe has faded out and is almost see through at times. I'v been told to separate him/her and treat it with maracyn one and two in case it's a bacterial infection or that columanaries (sp.) the back disease I think. What is your opinion on this. My only problem is that I don't think my mom will let me buy the meds because they will cost more than 10x what I spent on the fish and she wouldn't want me wasting my money on that.
