I noticed my fish were acting weird and was gonna do a water change. I noticed the water was way to warm. About 90 degrees. My heater is set to its lowest setting, it's a new heater and it had 4and a half star reviews. I unplugged it. Would doing a cooler water change shock the fish too much? Should I just let the temp cool on it's own? We keep the house at about 71 degrees so would no heater be ok? I cant afford to buy a second new one right now.
