So at the county fair there is a fish tank judging competition. I want to enter my ten gal. Is it too stressful to move them and then move them back again and then not eat for a few days because I will not be there? What is the best way to go about this as far as moving it? empty all the water and save half of it? empty all the water and save all of it? yes it is a long way away but i want to be prepared
