New Beardie Not eating

Hi so I just got a new baby beardie (this is her 4th day) and she’s not eating much I got her to eat one mealworm today but that’s it she also hasn’t pooped yet so I was wondering if anyone could help me out.
Tank size is 36x18x18 (40 gallon breeder)
Temp is 90 on warm side 70 on cool but I don’t think the thermometer is accurate
She is about 5 inches long and weighs 6 grams
Here are some pictures

Hi. Cute little fella. It's normal for them to have relocation stress. However you need a better Uvb light. A reptisun 10.0 t5 is what you want. Also you want a temp gun for accurate readings. Meal worms are not very good for him. Crickets, Phoenix worms , Silk worms and Dubai roaches are way better feeders.

Is that 10.0 Reptisun a coil? It looks like the coil box --- you want a Reptisun 10.0 T 5 or T 8-- here is some info on the UVB --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 6-8 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays-- her behavior is gonna change as soon as you get the tube in the tank ---

Ok, thank you! I will try to get her a new uvb light and different food and I will report back.

Also make sure you get a new thermometer. those dial ones aren't accurate and they dont give you the most important temperature, the basking SURFACE. Surface temp needs to be 105-110 for a baby. if your dial is only reading 90, then it's clearly much cooler lower down where your dragon would bask. They can not function at such low temperatures so you need to get an ir gun or digital with probe end asap. Then you can figure what your temps truly are and make adjustments from there.
