I am a new beardie owner and I was just curious about the different colors of bearded dragons. I got Rex from a pet store so does that make him like.. a mutt? I dont know the term but I have read a lot on here about people getting dragons from breders? Is this pretty similar to people who breed cats and dogs in the sense that you have your "pure breds"? It seems that some people have very colorful dragons so I was assuming people bred these dragons to produce vibrant colors? Rex was a dark brown when I got him but after a few sheds he seems the be turning a yellow or orange color. Is there a point when their colors stop changing or will he change throughout his life? Sorry I am such a newbie! Reguardless I <3 Rex!
