First of all I would ditch the sand and the night time light bulb- is it colored? Colored bulbs are no good and can cause long term eye damage - they need darkness to sleep like we do - it lowers their metabolism for them to get a better nites sleep -- use paper towels for a substrate - if you are feeding bugs on that sand its likely she has ingested some and it can cause impaction - second I would recommend upgrading her tank to a 75 or 120 gallon tank w/ doors that open from the front but first you need that
UVB light what did you order -- ? This is what is recommended on this forum--Which
UVB light should I use?
The best
UVB light is a ReptiSun 10.0 fluorescent tube HO (Or Arcardia 12% in the UK). Compact or coil bulbs do not emit the proper amount of
UVB light for a bearded dragon, and should not be used. Other brands, such as the Zilla Desert Series and ReptiGlo have been known to cause eye problems and other health issues with bearded dragons, and should be avoided. The reason that some UVB lights (Zilla, ReptiGlo, coils/compacts, ect.) are considered dangerous is because the wavelength of UVB that they emit is shorter and more intense than the wavelength of the "safe" lights (ReptiSun, Arcadia).
UVB lights should be replaced every 6 months. The T5’s are a strong bulb and only need to be replaced once a year – the T 8 every 6 months--- where as the T 8 are not as strong—they need to be placed inside the tank the T 5 10.0 bulb approx 10-11 inches from basking spot – the T 8 approx 8-10 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays-- this is crucial -- her basking temps should be 95-105-- for proper digestion of her food along w/ the UVB--- temps should be taken w/ a infrared heat gun from Walmart Home Depot or Lowes for around $10 -- they give the most accurate temps- a digital probe should be placed in the tank on the cool side for a temp of 80's during the day and not below 65 at nite---- I would recommend getting her a bigger hide - to me she looks miserable laying on the sand-- you can find some good decor from Petsmart - that stuff is easy to clean - you can go to the store and look if you have one where you live or look on line--- but first I would start w/ the sand and getting rid of that and the lighting - it is key to their overall health and behavior---
