First for the heating question, I have my leopard gecko in a 20gal terrarium, I have two undertank heat pads, one underneath, and one on the back wall, on the same end as each other, and right above them, I have a 25W Sunglo bulb. I know it should be 40W, but my fixture says 25W maximum, and I haven't had a chance to get a new fixture yet. Anyway, that side of the tank has only gotten up to about 78 degrees, I can't get it any higher than that. Should I cover the screen on that half of the tank? That's the only solution I can think of, since it seems like maybe the heat is just going straight out instead of heating up the tank enough.
And for the poop question, How often should my gecko defecate, and after it dries out, is it supposed to be super hard? I cleaned up one turd with a plastic spoon and it sounded like I had a piece of glass rolling around in it.... is this normal?
Obviously, I'm new to this....
Thanks all
