When we have a heat wave in LA, it goes up to 100F for several days in the summer, every other week or so for about 2 months (Aug-Sept). My question is: I do not turn on air conditioning during the heat wave since I am at work, do I need a cooling fan or chiller just in case for the betta?
Or should I just put blue ice wrapped in a towel against the tank wall?
Or should I just go without cooling for about 14 days total of heat wave?
I thought about adding a little refrigerate water but then the temp variation will be too drastic in a short period of time.
