So I just moved into college and the only thing we are allowed to have in the dorm is a fish. My roommate and I got a betta (named Rodger) and we absolutely love him! The only problem is that the water goes from adequately warm to freezing in about three hours-- we are assuming that it is the insane A/C in the building. We are running out of water conditioner left and right because we are constantly having to switch out his water from cold to warm (gradually, so as not to shock him). Can someone please help on an easier way to control his water temperature??
