Thank you guys for the advice, Kingcam in my opinion I do not trust the under-tank heat pads and my pac man burrows to escape the heat from what I've been told that would cause him to bury straight towards the heat instead. Bigblue That is such a great idea! I am going to do this without a doubt. What would be better to use plexi or glass? Heather what do you mean by spray and cover it?
