Hi Kurt,
Yes, I've looked at the care sheet a couple of times, which was making me ask about the temp. Yesterday I had this guy in a standard 12 inch height aquarium and the temperature at the bottom was hovering around 80 or so (not sure about the top, but he spent most of his time on the bottom). Makes me wonder if putting him back into a standard type tank would be easier for the heat distribution. This tank is 18 inches high...he is still sitting about 4 inches from the top. At the store he was in a very small enclosure by himself, maybe 10 x 6 and maybe 8 inches high...they had two 30 watt bulbs over him. If I move the light up further away am thinking it would make the bottom cooler ~ and thinking that isn't such a good idea. Here is hoping that he really is smart enough to know when he's had enough "rays". Will watch him for the next couple of days (when i can) and try to see where he spends most of his time. At the store they said he spent a lot of time in his water dish...maybe because he was cooking - not sure. Why do I keep thinking of him as a him??
