I was just looking at your pictures of your tank.
I'd suggest you get a second hid for the guy on the other side if it fits.
He needs a cool side and a warm side each with a seperate hide.
and eventually u may need a bigger tank?? 40G I have that looks like 20G???
I dont have any pictures of my setup yet but I kinda drew one.
And that is not a heat rock by the way!
I have a UTH pad on the hot side.
and I have very low wattage light bulbs. 40W I think.
Hot side is 90F and cool is 80. But it changes depending on the room temperature I guess...
I like your top because that must help humidity too eh!
I should do that to my lid! I have a hard time getting good humidity.
