Today I noticed one of my killies was "dead" and stuck to the side of the intake tube for the powerhead. I pulled him out and realized he had just died because he was still "fresh" and had not rigor. Well, while I was admiring his coloration in my hand, he twitched. As soon as he twitched, I put him back into my "fuge" so that he could get a break. The "fuge" is in a high flow area, but does not get a lot of current because of the way it is designed. However, it does get a lot of Oxygen. He has been in there for several hours gasping for breathe and slipping in and out of conciousness. What else should I do to help him out?
