The female in the pic below I purchased from Gecko King. When I saw him post 1.3 for sale on the classified I had to have them. She is a sweetheart and has layed 2 perfect little eggs. Looking forward to seeing what colors come out.
As for finding the colors you want you just have you look around and contact breeders or go to a reptile show. As it has been said before babies do some color changes as they grow. If I could use what Forrest Gump said..."Cresties are like a box of chocolate, you never know what you are going to get." :o)
