I have gotten out of the habit checking my fish tanks temperature with touch to the tank digital thermometer that I have except for water changes. It's pretty warm out and I decided to check the temps and it's way up but I didn't know it because the thermometer stops at 86.
I have some of my fish in bathroom which was advantageous during cooler weather as it stays warm. The two fish that I recently rescued that don't have heaters are at 78. My heaters are not adjustable. I am thinking of unplugging them. Before I do that I have put scarves on top of the tanks and opened the door to see if I can cool it off to an acceptable temperature. My fish are acting very normal. I will be up later tonight to see how it goes.
I thought I'd warn you if you are relying on stick thermometers to give your temperature and you have not been watching it to go look if you are getting warmer temperatures. I am probably going to move my fish downstairs.
