I sure hope you are not correct in that all Comets and goldfish turn out to be solid red or solid white! I have some that were born white with orange/red spots and others orange/red with white spots, and they have not changed at all. I even documented how each one was marked. I have babies that look like their mothers! I have an identical Shubunkin that looks like my original Shubie, and another goldfish I bought because it had a white belly, white ends to all the tails, and white lips. She is my other known female, and she has a twin for a baby. The colors have not changed at all. I think solid fish remain solid, but I also think that patterned fish remain patterned. Koi are a different story, at least with some of the color combination types. Also, the black babies all turned to be solid orange/red. I have 2 that have not changed yet, they are still black, but are very small, 1.5-2" long or so. They will be orange when they get a little bigger, probably by spring.
When I chose feeder fish my local pet store would let me choose them and pay the low price for feeders, but he had it on the tank that if you choose them individually, you had to pay premium, but it was never $5. I think he charged 20 cents for feeders, and 45 for the individually chosen fish. I always chose ones with more patterns and colors, and always long tails, the comets variety, rather than the common goldies. There were a couple that I picked out at Pet Smart that were in other tanks with the other tropical fish to help keep the bottoms cleaned up that I bought for the same price as feeders, since they were 3-4" long! They were commons, and that's how I got the common shorter tailed goldfish. Also, my friend had 2 large goldies that were solid orange. One is common, the other is leaning toward the Comet, and I suspect one of them has been involved in the reproduction as well. My favorite Comet is one that came with my 55 gal aquarium, and it's very much a Comet, VERY long flowing tails, and has a red spot on top of it's head, otherwise it's solid white. (Would be called Tancho if a koi.)
