So the other day I was doing a 50 percent water change in my aquarium and I take my fish out so he won't get sloshed around. After 10 minutes of trying to catch him in a net and putting him in a separate container, he swims, jumps, flares, and starts attacking the container. I am a little worried about it because I do not want him to seriously hurt himself. I need to get water changes done, but I do not want to traumatize the poor little guy either.
So what I am asking is if there is anything I can do to help him cope with all of this when it comes time?
