There are no hobbyist permits for either asian aros or SHs. Asian aros are federally banned because their inclusion in CITES also makes them fall under the US umbrella of the Endangered Species Act and the Lacey Act. SHs are federally banned due to being a prolific invasive species listed as detrimental to native species and biotopes.
+1 This is why. It's not like its one law banning them - its an entire network of laws. Starts with cities and works its way down. In order to get them pulled you would have to tackle Cities to get them off their list and work it from there. It would take a lot of money and research.
As for the reason the farms do not breed and contribute to the wild stocks is simple, they make a ton of money selling to the hobby. Many farms did start out to breed for the purpose of repopulating the species, then they realized they could make a lot of money selling them off instead. This does however help in keeping people from taking the wild stock.
As for getting a permit - it will probably never happen. The loopholes that they did have are way gone. If I remember correctly its probably been something like 25 years since the last permit for an Asian aro was approved.
It is also not recommended you keep illegal species - and this site doesn't encourage it either.
Fish and Game check internet sites regularly - including this one. Many people get busted. In your house or not - its not like they can't find you to find out. Its not a small offense either, it comes with a hefty price tag/jail time.
