umm - that inbreeding info may or may not be true (i wouldn't really be surprised either way)
however, i think neons are one of the easiest fish to take care of. i'm not sure if i got "wild caught" or bred neons, but i know they were pretty cheap, so probably bred. i've had no issues with them, and they have been in my tank for a while now.
as for taking careo of them, do the same thing you would for any tropical fish, keep the water clean, feed, keep at a good temperature. there's lots of info on this website about doing all that, so i won't go into detail here, but feel free to ask any questions you might have
