I'm in the process of setting it up right now, so there will be photos very shortly. I took your advice on not using sponges, so there is moss in the bottom of the "pool" and a log to climb in/out. There is a foam insert in the tank (one of the decorative ones) and I simply used scissors to cut out a chunk for the bowl to fit in. It worked out nicely.
I'll look into the roaches. My boyfriend is going to kill me, though. He's terrified of roaches. I'll just call them "crickets" around him.I figured I'd be buying a variety of worms but I was hoping that I could get the actual beetle larvae.
The heating pad you mentioned sounds absolutely perfect for me. I keep my apartment at about 74* year-round, and since the lizards like it cool anyway, I wouldn't even need 10 more degrees. In fact, I may be ok without anything at all, though *ideally* the temps should be about 76-78. Do you think that little difference in temperature will make a big difference in health?
