hello
ok the main thing here is the fact you do not have a uvb fluorescent tube, this is crucial to their development along with the correct calcium and vitamin supplements your beardie will then thrive.
so you need a reptiSUN 10.0 flourescent tube, please do not mix up the reptisun to the reptiGLO tube, nor get any kind of compact or coil, they are all bad for your beardie. reptisun only.
along with the uvb tube, you will only need one white basking bulb, as long as you have a white bulb in conjunction with the tube then your beardie will benefit. having said that if your not getting up to temperature then perhaps 2 bulbs next door to each other as to act as one, you only need one basking spot you do not want to overheat her with many.
so you have had her 5 months and shes 14" long, is that from the tip of the nose to the tip of tail? how old is she?
a baby or juvie should get calcium powder or liquid 5x a week and multi vitamins 2-3x a week, an adult has to have calcium 3x a week and multi vitamis 2x a week, get me so far? along with this and the correct uvb they should be fine. oh and obviously high enough temps and some nice
bathing to prevent dehydration.
great she eats and poops fine and is active.
hm yeah seeing her reflection and shes acting towards it could stress her out, you could even get some nice background paper, with rocks or desert pictures on and put it around the back and 2 sides so she can still see out the front, some people say the backing paper actually calms them, not sure how true that is though. i have backing paper for my 2 but have never gotten round to putting it up as it means a lot of moving with the tube, bulb fittings and wires. and like i said before i doubt she would have been getting the correct amount of uva/uvb through the glass so all of this could also put a damper on her health. i know its a lot of info and it can get a tad costly but in the long run its worth it and once you have everything your little one needs you dont really need to spend anymore money only food.
hope im helping.
