I know there are tons of these on here, but I couldnt find one to answer exactly what I am asking, so I figured to start a new thread.

I recently put my lil dude in a plastic tub instead of a glass aquarium, and I put the probe taped onto the bottom directly, and it gave a reading of 95 degrees. Then I was thinking " he doesnt even touch the direct bottom". I put paper towel down, and then some aspen shavings. So I taped the probe to the paper towel, and now have a reading of 90 degrees, which sounds better.

So do you think the probe should be taped to the direct bottom, or the paper towel? Thanks
