This question has bothered me the last two summers. When a fish died in my 10g tank, it was usually over the summer. (The exception has been newly purchased swordtails that died within 24 hours of coming home). I remember danios and platys dying both summers and I wonder if they got too warm. I keep the tank heater at 77 degrees but my house is not air conditioned and it can get pretty hot during July and August here in Ohio. Now my fish are all in a 75g, lighted, planted tank. Should I just unplug the heater for the summer or does the heater turn itself off when the temp gets higher than 77 degrees? (Its a Ebo-Jager brand-I no longer have the directions that came with it). On really hot days would a fan trained on the tank help? Should I keep the tank lights off too during the hottest days and will this effect the plants (mostly low light ones) adversely?
For example: today's temp is upper 80's and the tank thermometer reads 79 degrees, two degrees higher than normal.
