I bought fish from there as a kid. Anymore, I think they shouldn't carry them as the majority of them don't have just one person who takes care of them. So every employee who happens to be in the vicinity of the tanks is the one who has to help the customers. Usually, the fish are pretty healthy when they come in. But after a few days, they're not doing too hot.
I, personally, am completely against them having a fish department.
But QT any fish you buy, no matter where you get them from. YOu may never have anything happen, but then one day, you may bring home the an Otocinclus with a case of ich that you hadnt really noticed, and BAM!!! You're tank is in jeopardy over a $2 fish!
