It has been 6 months since I changed the lightbulb in Tarey's tank. I got a Reptisun bulb this time (it was another brand last time- I think it was All Living Things). I have multiple shelves and one is 6 inches from the bulb. She used to lay on that shelf all the time and now she hasnt been there at all since I changed the bulb. So I need to lower the shelf a bit? Maybe it is too close to the light.
