I'm having skittle heat wave here in NY. I normally keep my tank at 79 deg. But for the past 2 days it's been around 82 Deg. I have my canopy open and the lids open and the room has a powerful ceiling fan. At this temp should I be worried and go out and get a small fan to clip on to canopy and blow across the water or should the fish be fine? If I'm fine now at what temp should I start to take more action?
