I have a large 600 gallon pond with 4 koi, except one koi has been beaten by the others to severe injuries. I am treating both the fish and the pond in case it was any sort of infection that caused the bullying. I want to bring the 3 inch koi with me to my single dorm room in college and the tank limit there is 10 gallons. Could I keep him there for a year and then get a much bigger tank when I get an apartment later?
