I got him sunday he ate 2 pieces of worm for me and he was full, hes pretty small. The second night he went and chilled in his water for about an hour didn't eat then went and plopped his but under a plant right under the lamp, the plant has nice leaves so the heat and light don't beat right on him while hes there. He ate 2 small wax worms last night but still hasn't moved from that spot and today he completely buried himself. So everything seems ok to me I will wait and see what he does tonight. I just don't want to be hurting the poor little guy but I need the extra heat from the lamp because hes in the basement because that's the most low traffic area. And its not all that bright when dimmed and I just looked at this box again for 100th time and it says nothing about uv. Maybe if your not sure Lija or someone will hopefully see this. Oh man, what to do when you live a shoe? L.O.L I just ran downstairs to take a picture of the tank in the day to show how much of the blue light shines during this period, I turned the flash off so you can actually see it. I tried to do a night time one when its dimmed but its pointless because you cant see anything. This may sound like a basic question but why is it purple to my eye but blue in the picture? what color is my frog seeing? And if this bulb ends up not being good for him can someone recommend one that can stay on at night when hooked to a dimmer? I dont know why this picture looks black and white but thats how much of the heat bulb shines in.
