Hey everyone, I have a 20 g that is home to three guppies and two platys. I also have a 10 g with a crowntail betta. Both tanks are cycled and the temperature is normally kept around 79 for both tanks. My apartment is normally kept at 69-70 degrees, but in my apartment building I believe the buildings central air system has quit. Its around 82-83 outside and I am on the top floor. So at the moment in my apartment it is around 82-83 degrees which are making my tanks this temperature too. I have looked on the internet and the rest of the week it is suppose to be 86's and up. I am just worried about my fish. I have already made a call to the front office in my apartment complex, but it doesn't look like they till maybe tomorrow (not sure what time during the day). I am just wondering if anyone has any ideas of how I can keep my guys from getting too hot. edit: I forgot to mentioned both tanks have airstones and I have already increased the flow of them on both tanks. Thanks!
