But, just to add to the conversion, if these are indeed just short bodied red devils, treated to cause infertility, how come the infertility rate in male blood parrot x blood parrot fry is still so high? I have seen several cases of people getting their parrots to breed viable fry, and yet the fry still aren't consistently fertile.
I suppose it could be a genetic anomaly, but short bodied convicts are just as fertile as normal convicts (I had 2 pairs, they spawned like crazy - though most of the fry got eaten), and my LFS has a ton of these from people that have bought them and had batches of fry. And those fry go on to other people who have a ton of fry also.
Fancy goldfish also have the ability to spawn viable fry, as do their offspring.
SO, if it is indeed just a short bodied red devil, and the people producing them are just breeding for this trait and chemically treating the fry to cause infertility, how come anyone that breeds blood parrots with other blood parrots has infertility issues in the fry also? Wouldn't it stand to reason that someone that got fry would be able to start producing them like crazy?
