Nah, I personally do not "discipline" my fish. My post was just for humor. I feel they are programmed to do what they do, so you can't really alter that.Hmm, I thought that was the whole point for people keeping aggressive fish was getting off watching them constantly fight and bicker. Not a fan of this myself but it seems to be a popular stance around here.
Or stick the bag in the freezer for a few.A plastic bag for time out is ok, but kinda soft. I would use a blender as a time to really get the message across
