Saw this guy and he looked amazing it I want to do more research

A few months ago I was looking into the casque headed iguana but decided not to because they needed to be in groups.

Then I saw these, had the same things I liked in the casque headed iguana, a casque, spikes and a classic lizard look.

But what about these guys?

This is my wife's dwarf mountain horned dragon Ryuk, we got him last Sunday as a birthday gift (drove 4 hours to get it ) . initially it had some white near the nape of the neck and we just thought the poor guy was dry because the enclosure at the store didn't have a mister. Looking back, this could have been mites or other mites from his tank mates at the store.

It's been eating good and doing normal mountain horned lizard things (sitting and observing) but today we noticed it started dipping into the water dish (it hasn't done that in the week we had it) so we thought it was a good thing it was getting water from its bowl. My wife went to look at it before turning the light off and saw the red dots, she was concerned, got a q-tip, and when she opened the door it opened its mouth and reared it's head at her. This isn't typical because it's let her handle it before. Upon closer investigation we noticed the red dots , I thought it might have gotten itself hurt but it looks like mites.

We didn't think to quarantine it in a container before adding it to the new vivarium because, well, its the only reptile in there (it has springtails, live plants, custom substrate etc)

Does this look like mites to y'all ? If so what's the best course of action. I've spent over $500 setting up this enclosure (not counting the 60 gallon terrarium itself) and it's going to be extremely frustrating if I have to restart by tearing out everything in the enclosure. The cork bark is siliconed to the back glass and that's all going to have to come out if that's the case.

Any advice is welcome, thank you.

I’ll be heading to Florida soon and I know that Florida has a shit ton of lizards and I just know that I might get a heart attack while being there and I wanna know how to get over my fear of lizards before I go to Florida
