'Tan albino'? I am guessing you mean it has red eyes. I only have 'fancy' rats, most people call any rat that is not albino fancy. I have gotten all my rats from pet stores. I got a black dumbo that carried the blue gene from Petsmart. Now I have a combination of dumbo, top ear, black eye, ruby eye, odd eye, manx, blue (russian and american), black, beige, cinnamon, agouti, blaze, berkshire, hooded, variegated and irish. And probably others I am forgetting right now. There is nothing wrong with getting pet store rats to breed, and you can end up with some really cool looking rats. Just make sure to check them out and make sure they are healthy and not nippy before buying any rat. I just picked up a silvery blue blaze berkshire male from a pet store a few weeks ago to mate with a self russian blue dumbo female. Can't wait to see what they throw.
