Well, that's great he is okay. You should keep the heater on at least 78-80 degrees, and keep a thermometer in the tank too so you can know the temp at all times. It should only heat the water up slowly. You could try putting him in a temporary home while the heater warms the tank to the right temp and then let your fish float in a cup in his tank (like the one's you see them in at petstores) for an hour to get used to it.
