It's a good point but think about how many of those breeders are just in it for the money?...and think about how flooded the market is now as there are so many breeders and advertised animals stay being advertised for months on end.... the same thing goes with all animals (geckos, bearded dragons etc) that get bred in high numbers and surpass the demand. This leads to hatchlings being killed (there was a thread about this) and to me, that is not right, that simply displays some people's greed and shows how truly passionate about reptiles they are. When it comes to breeding, people should interpret the market based on past years and be able to make an educated guess at how well their progeny will sell. If they believe hatchlings won't sell for a price they want, they shouldn't breed them at all unless they're prepared to hold them back. The same thing goes with morph breeding, people expect to breed the best either to a) make a name for themselves as the producer of a new morph, b) have a genuine interest in creating and adding additional colours/patterns etc or, c) $$$$. Then, when something goes wrong and they breed a normal looking animal, they get killed faster than they hatched (especially in large clutch producers such as pythons [additionally, there was a thread about this]).
Sorry to get so far off topic but personally, I would be happy enough to never see these blue-tongues in private hands.
