Okay in Bridgeville (part of Pittsburgh, PA) was this pretty good fish store (pet supplies plus was the same of place).
The owners of the store were not like fishlore, but definitely not idiots.
It was a nice place that was close, and the tanks were well maintained (i never once saw a sick fish while in the store).
Well the place changed ownership and some of the guys that ran the aquatic section were no longer there, though now I don't know who is running that section now.
Let's just say I have never been so sick in my whole life..
I will spare the details, suffice to say that I will not be going there again...
I may look into laws on fish keeping.. I mean sure they aren't as bad as having the wrong the species kept together, but my god is everything else bad

... it's really tempting me to find out if they can get in trouble for the way the tanks are kept..
