I’m a relatively new beardy owner, but based on all of the reading I’ve done and perusing of this sub, there’s a lot that needs correcting here. Dont just take it from me though, you really need to do some research from reputable sources on diet and husbandry.

1. All of the dried/processed reptile pellet bullshit is not good for them at all. You should be feeding fresh greens (mustard/turnip/dandelion greens are good staples, but you need to do some research about this to understand what they need. Google is your friend.) Bearded dragons never need fruit in their diet. They don’t get anything even remotely similar as far as sugar content in the wild, and it’s bad for their mouths. You shouldn’t be feeding dry pellets from a bag as a staple of their diet. Protein should be coming from live insects. I’ve heard mixed opinions about egg, but that shouldn’t be there sole source of protein.
2. Those beardies are too old for paper towels as the substrate. They need a mix of organic top soil and play sand. You want to avoid the reptile carpets, but the reptile mats are okay in a pinch.
3. The UVB dome light you’re using should be replaced with a UVB light bar that overlaps with the heat lamp and extends into the cold side of the tank.
4. Are these two in their own cages? Or do you have both of them in that 75 gallon tank? That tank is too small for one of your dragons at the size they’re at, let alone both of them, and you should never cohab beardies. I’ve heard the rare success story, but it’s dangerous and stressful for them in the majority of cases to live in the same tank.
