Everyone has to learn what is legal and what isn't sometime. The topic of Asian Aros in the USA is brought up a lot here. As far as I can tell it's from people researching them. It might be easy to do a search to find out info on them, but what's wrong with starting your own thread and asking your own questions? If the frequent questions on them bothers you, move on. There is more to do here than comment on illegal fish in the states.
To the OP, unless you have a 6x3 tank I would not get any aro. A Jar would be OK in a 6x3. Silvers and black aros need a 8x3 IMO.
