Pandas breed well in tanks, so you might have better luck buying online. Just look for "tank raised" ones. Bad thing about online, besides shipping costs, is that you can't see what you're buying (usually). I try to buy from individuals though....they normally ship good (depends on seller, but overall I've had good experiences with individuals).
Good luck finding Hastatus Cories.
I'm surprised the LFS had them. They are kind of rare IME.
