They're cheap because they cut costs on fish care and quite frankly they don't take proper care of their fish. But, they get alot of species that you can't get anywhere else in the wgtn region. There's ALOT of dead fish in their tanks, I've walked in their alot and have seen 4 1 foot long pacus in a 3ft tank and fish that have been ripped to shreds because they place them in with uncompatible species. Even Gavin's (the huge giant gourami) tank is far far too small for him. I go there occasionly, and I haven't had any problems with their fish as I've looked for normal behaviour before I buy them.
I didn't see the post that was deleted, but I think, providing that the post isn't a personal attack or anything too maliclous, deletion should be kept to a bare minimum as it is censorship and freedom of speech should be valued.
