Here we have a great example of "Pet store Misinformation"...
Ok first of all, Im guessing you didn't read up a lot on this forum before getting your beardie.
1) I don't recommend using the (most likely sand) substrate that came with your kit..
2) Your probably noticing your beardies eyes being shut most of the day (due to the bad
UVB bulb that came w/ your kit). So I would recommend buying a 10.0 reptisun ASAP
3) Im also sure your kit came /w a night bulb, which I recommend you replace /w a Ceramic heat emitter (if your temps get too cold at night).
4) Since your tank isn't getting hot enough you should either get a higher wattage bulb or moving your bulb closer to the basking area.
5) Make sure the water in your bowl isnt too deep
6) Beardies can't sense heat from their bellies(from what I've read), so make sure that the rock doesnt get too hot
I know this is hard to hear but if you want your beardie to thrive your going have to read up ALOT on what to change/ do in the future.
Which petstore did you get your kit from?
