The whole "everyone will start making them" argument is ridiculous. You can't just start making animals that have a recessive trait combined with multiple other traits. It takes YEARS. One year just to make the morph het clowns, assuming you already have a BREEDING size male clown and BREEDER females of all the other morphs involved. Then you would still have to raise up the morph het clowns to breeding size. Why do you think we haven't seen the market flooded with panda pieds? Plenty of people are working on it, but it takes TIME. Brock blew everyone away with his lesser clowns a year ago, and the market hasn't exactly been flooded with lesser clowns yet, and it is just one codom with one recessive. We will probably see some in the 2011 season, but it is safe to say that "everyone" hasn't got that far yet.
That being said, I can't blame Ralph for not releasing the recipe before he has even sold the animal or any sibs that would be helpful in producing another flatline, especially right before breeding season. Why not give yourself an extra season lead on the competition.
