My beardie is suddenly really dark!

[Mocha McGillian]

Recently, my bearded dragon has turned really dark all over. Before he turned dark, he was really bright yellowish and I didn’t have this problem with him before. Occasionally, he also goes into one of his hides and will sit there for a bit. My current guess is he is really stressed about something but I don’t know what. I recently took him to the vet and he was prescribed Panacur and he’s been given 0.2ml for two weeks now. Additionally, he started shedding on the front of his face and hasn’t shed anywhere else yet. For context, he’s six years old as well and I’ve had him for about half a year now.

Tank Setup:
Basking Side is around 110 degrees and the cool side is around 85-90 degrees.
Humidity varies from 30-50 but is mostly under 40.
He has a UVB light that is not coiled or anything.
His tank is 40 gallons with a tile substrate.

The first picture of him is today on August 28.

If ur taking temps with just the stick on ur temps are inaccurate, you need a digital probe for accuracy, im thinking ur barely getting 90f , hes dark cause he’s trying to absorb heat, when they’re hot enough they open their mouths and turn to their “lighter phase” if his beard or tummy are dark then id be worried.

Also in my opinion he does look a lil thin (not under weight, but thin) and he is dehydrated (wrinkles in the skin and strands of saliva are giveaways)

I don’t think he has improper heating or dehydration. I do have a digital thermometer to track his temps and he does bask under his light and he was really bright before he turned dark. Also, I pinched the skin on his back and belly to see if he was dehydrated and neither side tented or stayed pinched.

Just to be safe though about the temperatures. I took out the bulb and switched to his backup bulb.

I apologize If i came off as judging you, he must’ve just been in a weird position, and it is important you have a good digital thermometer may i see what kind?

It’s all good. I don’t think his temps are what is stressing him though because he has been using his hiding spots.
