UVB for bearded dragon

What should I change my bearded dragons UVB light to be? A few months back I changed my tank from a 40 to 120 gallon. I have been using a 24 inch hood with a T5 HO UVB bulb on top. However, my beardie hasn’t been eating and I now think that the mesh is too fine for him to receive proper UVB amounts. If I am to mount a bulb on the inside, what should I use? (and should it hit his basking spot? From what I’ve seen things say XX inches from basking spot, but isn’t that where the heat has to be?) He has a log on the cool side that is 15 inches from the top, and his basking spot is 19 inches away at the bottom and 7 at the very top depending on where the light will be hitting. Also, do I need to factor in how high he’s holding his head? Any help is appreciated, I want to make sure that he’s getting sufficient UVB. Thanks!

Your UVB needs to be inside the tank directly over a piece of basking decor - try and get it as close to your basking light as possible if not set up a second basking area w/ the light on top of screen behind the UVB get temps w/ a digital probe thermometer - the screen is blocking approx 30% of the rays --- you can hang the UVB w/ fishing line --- picture wire hangers I recommend those they are bendable- 3M velcro fasteners or long plastic zip ties --- you want the UVB approx 12-15 inches I recommend around 13 inches directly over a piece of basking decor

If I were to mount the T5 HO on the inside what would the distance need to be? I want to make sure he doesn’t get too much exposure. He’ll lift his head up and that adds a couple inches too, and I don’t want him to be too close. What would be your recommended distance with that in consideration?

UVB and the basking light should overlap. Like being outside, you can not choose between heat or uvb, if you are in the sun you get both. Bearded dragons have lived in the desserts for a long time, if he gets to much uvb, he'll most likely just seek shelter and hide from it.
Also a lot of dragons do not eat a bunch this time of the year, so that alone might not be a strong sign that something is wrong to begin with...

i feel so sad reading your about me 😢
Clapton is acclimating okay I think. He's quick as lightning so I'm not sure how much I should bring him out of his house yet. He's not at all interested in his salad though. I wonder if I should change what I'm giving him. Least he's eating his crickets.

Things to do:
Buy calcium powder
Material to raise surface for basking spot
Scenery decals for back of tank
Taking my beardie for a walk
Hi everyone, I have a question please. I have a thick branch I got from outside. It has been in freezing temperatures so I know that it is insect free. I took it off the ground and sat it up during a night we got down to 15 so the entire thing would freeze. Well tonight I put white vinegar all over it too cleanse it since it won't fit in my oven. Do I need to rinse with water tomorrow or is it fine left alone dried?
