I have tanks of Mollies normally at about 76F. When it starts to get hot over 88F, what do I do about the fish? I live in NH, don't care much for AC, but do have lots of windy days with the wind from the wide open marsh. It keeps things fairly cool for me, but the ambient temp is still measuring in the 90s for a couple of weeks. Will fish be OK, it won't happen quickly but during the heat of the day, what should I do? Are they OK to just handle it themselves?
