about 4 years ago i housed a breeding pair of beardies with a male mali. They got along great and they didn't attack eachother. The only reason why you shouldn't do it is because of parasites, but if they both are treated then i dont know why you couldn't. I housed them together for 4 years with no problems. I would feed the beardies in a container outside of the tank and feed all of them veggies inside the tank. Lots of people will not like it if you house them together but i dont see a reason why you coudn't house them together. People will tell you parasites, pocking eyes out, and they aren't together in the wild but with my experience the beardies had their eyes, they were all extremly healthy(took fecial samples to vet) and since this isn't the wild and it is captivity i think there is no problem. They might be agressive for the first few days, but after that they should be fine. After a while they will start basking together, sleeping together and eating together. So if they both seem healthy slowly introduce them to eachother and if they get along put them in a tank and hopefully they will be great cage mates. But you have to make the basking spot i think 115-120 so the beardie and the uro should be fine basking there.
