Thanks for the advice! I'd read a bit about that, and the temp is usually a little over 80, but it fluctuates. It's a pretty cheapo thermometer/hydro gauge, so I wonder about the accuracy a tiny bit. Once in a while I check it and the temp has changed, once I caught it at 90 or so and closed the curtains to lower the temp, but I worry a little. After that the temp went down to 70 and I had to reposition my lamp. What some ways I can keep it more constant? I'd imagine if he gets too hot he'll move to the side the lamp isn't on or get in the pool, but I'd prefer if he didn't have to. Also, my lighting is currently a 50w daylight heat bulb which shines on half his enclosure, I meant have that in the original essay post.
Edit: Almost forgot, I read on some site(s) that pacman frogs don't care about decorations, but I wonder if maybe prettying up he area might make him happier and more comfortable.
