So I had two male and two female azureus in a 20 gallon tank. About two months ago, I noticed that one of my females was getting thin so I pulled her out and gave her a 5 gallon tank by herself. She continued to drop in weight. I have tried absolutely everything--feeding multiple times during the day, extra misting, even diluted gatorade--and she still will not pick up in weight for more than a day or two. I have heard a little about "wasting disease" and I was wondering if this is sounding like a possibility and if so, how should I proceed?
Thank you all so much for your help!!!
Luke.
