They just recently took out their SW selection and replaced it with freshwater fish and guess what fish they replaced them with? MORE tetras!
I'd look on the bright side of things: At least they aren't selling SW fish anymore! I've often felt that unless a pet store is committed to doing a good job, they shouldn't bother selling SW fish since they are generally harder to keep. Not to mention most are wild-caught. At least tetras are farm-raised in SE Asia, so if a few thousand die in crappy pet stores, the species will probably survive. Kind of a grim outlook though.
