I remember reading a longer thread about temperature a while back, before I joined the forum, that got me thinking about my own tanks temperatures and a video on tank vs wild temps from Aquarium CoOp. I obviously want to aim for healthy growth but don't feel the need to push pedal to the metal and sacrifice overall health and longevity. Plus, if a heater malfunctions in the OFF position it seems fish that are adjusted to a middle ground temp wouldn't shock as much since the temperature wouldn't drop as much running at 75 vs 78. I have my heater connected to an InkBird so I can check with my phone the temp and receive alarms should the heater fail in.
