I'm no expert, but as I recall from high school biology, the gene for albinism is recessive in nature. Thus a normal colored fish may carry the gene. It also follows that both parents must carry the gene in order to produce albino fry.
Did you obtain your male and female from the same source at the same time? If so, chances are they are from the same brood (i.e., brother and sister). That would certainly explain why you happened to obtain two fish that both carry the albinism gene.
I don't know but albino socolofi are in every LFS around here as are albino auratus. I have some of both but no fry from them yet. I bet by there being so many of them out in the stores now that it's going to get pretty common for fish to throw them. Just my opinion and I could be wrong.
