I'm rather curious about the bearded dragons.. The snake cohabbing has been beaten to death and back (and, I agree, just not worth it... If you want snakes that can live happily in groups, get rid of your corns, etc, and get garter snakes. Corn snakes, Hognoses, and boas just are not made for communal living, no matter how happy it makes you...), but I'd like to get a word in regarding the beardies.
It has been brought up already, bearded dragons, like snakes, are not social creatures. I can vouch for this: At one point, I had 3 bearded dragons. The two females came to me as adults already living together, and showing it: One was much larger than the other, both were missing a fair chunk of tail, and one had a permanently deformed hand--missing most of one toe, with the neighboring 3 toes stunted and bent at odd angles from breaking and never being properly treated. I chose to leave them together, though, under close supervision, since despite past injuries they seemed to do alright together. They proved me wrong, some 2 months into my care: The smaller female attacked the larger, injuring one of her feet. I was lucky it wasn't worse (i.e., she didn't sever another toe, and, for that matter, didn't bite her in a more delicate spot--like her head), and smartly chose to separate them to avoid worse happening.
I tried housing them together once again, some 6 months or so later, due to one of their enclosures getting broken beyond repair. They did NOT enjoy it. One refused food for the first few days and only picked for a week (both, when housed alone, are total gluttons and eat everything in sight), both were edgy and nervous, and this was all in a 6 foot enclosure: In theory, big enough for 2 dragons. They would avoid each other during outdoor basking sessions, too, whether or not they were living in the same enclosure at the time. Given the chance, they went their separate ways and avoided the "competition."
As a matter of fact, I eventually chose to rehome both the females for the simple reason that maintaining 3 bearded dragons, housed separately, was too much work for me. Could I have put them in the same enclosure? Saved so much of that work and made having 3 "doable"? Sure... But it would NOT have been fair to the dragons, so I chose to find homes for the two girls, where they would live happy, spoiled lives, away from other dragons.
Another instance I've experienced: I worked at a pet store for the better part of a year, and we usually had a batch of 5-10 beardie babies in stock at any time. We never, ever had a 100% survival rate while I worked there, not even close. The reason? Bullying issues. Beardies are NOT social, and their instincts tell them to dominate other beardies in the area and restrict them from food. Even when we got down to just 2 beardies in the enclosure, we'd still have that problem, because that instinct is still there. The more dominant of the pair would still bully the other quite literally to death by starvation. The only time we were able to totally avoid problems with the beardies was when there was only one in the enclosure. It would thrive, do very well, and the only difference between then and when there was more than 1 beardie? Numbers! ONE beardie does GREAT. MORE than one, they do awful!
Now that my rant is past, I'd like to ask how big your enclosure is. You said it's an octagon with 19" sides, but, quite frankly, my math sucks and I can't find a single math calculator that can solve it for me. What is the diameter, from one side to the side immediately opposite? How many basking sites do you have? How big are your beardies, and how old are they? What sexes are they, if you know?
I'm tempted to go so far as asking basic care questions here... Whether you even have UVB lighting, for example, as, if you haven't seen significant bullying issues yet (one growing exceptionally larger while another fails to thrive; injuries; etc), I'm willing to bet there's something wrong with your care regiment that has them regarding each other in such a "docile" manner.
I'm probably wasting my time, I know, but I feel it needs to be discussed... (Forgive me if it has been already; this and the home study are the only of this guy's threads I've bothered reading.)
