Actually, I honestly wouldn't trust the pet shops at all because it's obvious that they have given you some really bad advice. :? Also, there are MANY problems with the setup,
1: The red bulb is useless. They can hurt the beardies eyes and disrupt their sleep patterns.
2: You have a coil
UVB bulb. Also get rid of that because sometimes that can cause extreme eye issues and sometimes blindness. What type is it?
3: The tank is WAY too small and you will soon have to upgrade it to a 72-120 gallon tank once she is older. I'm Assuming it's a 10-20 gal tank right?
4: All the loose wires and metal wire things could Invite her to climb on it and possibly get hurt,
5: The bulbs are WAY too close to her, Especially the red bulb since they get EXTREMELY hot and she could climb up one of those wires and onto one of the bulbs and get burned.
6: There really is no need for a water bowl because it's rare for beardies to drink from it, If it's not changed enough it can become a bacteria farm, and sometimes baby beardies will sleep walk at night into the water dish (and your water dish looks quite deep for her) and can either drown or have their body temperatures drop down to deadly low levels.
Here's some good examples of a good setup, Hopefully it'll give you some ideas:
View media item 60902 This is Cisco's tank,
View media item 60757 Daisy's tank (she's the only one with a lid on her cage because she's a live-wire and has nearly escaped before when I forgot to put the lid back on),
and I Do not have a good picture of Loki's current setup since I need to add some more things and upgrade the size of the tank.
I Hope that this was helpful for you.
