Some folks put down some ceramic or porcelin tile over the heated floor spot to give a little more "heat mass". This is a really good idea to do, because glass can get hot.

I don't use glass tanks anymore, but when I did, I would use a few small dabs of water-based kitchen/bath adhesive/sealant to hold the tile down on the glass. Easy to remove if you ever need to but holds nicely.
