She didn't kill the fish just because of the ich. She treated with daily water changes and aquarium salt and the temp of the water was brought up to 80 at all times but we're pretty sure now that there was something more than ick because for the past 2 days he had been at the bottom of the tank, laying on it's side barely breathing (we could scoop him up in our hands, no flight response) and there was a white velvety-like thing growing on him. Yesterday he looked so bad we didn't think he was going to last the day. So there was ick but there was also something else wrong with him... velvet? internal parasites? it's hard to tell but he was extremelly sick. He was also bloated and very thin at the end .
He wasn't JUST euthanasized for fun. The fish was in pain and there was absolutly no improvement, he was deteriorating every minute, that's why he was humanly euthanized. Believe me, I work in a veterinary hospital and see people everyday that want their pets euthanized for the wrong reason, I wouldn't have let her do it if there was a good chance of bringing him back to health.
Just wanted to clarify.
P.S. The photos shown on the first page were taken some time ago and the ick was barely starting at that point. He became covered with it and a lot more bloated than the last picture. He was a sad sight.
