Ok I have a question for you all, if you can help me. I love Fancy Gold fish and have recently acquired a 20g aquarium and several goldfish that (a mother's day gift) that I found out, through this site, that my tank will become too small for. I am now considering either rehousing most of them or getting a larger tank. That problem solved, I have another problem. How do I keep the water "cool" so to speak. It got up to 80 degrees. My tank is in a good area, but recently the temperature outside has gone up and so did the temp in my apartment. I don't have central air so I am not quite sure how to get the temp to go back down. Other than buying a fan to put on the tank, I don't know what else to do. It's only been a less than 24 hours since it hit 80 degrees in the tank but the temp has been steadily rising since it got set up on Saturday. So far the fish seem to be doing well but I am worried that they might die. Even getting a bigger tank won't help me much if i can't keep the water cool enough for them. Please help!!!
