Pet World on West Mercury Blvd. It's in the Food Lion shopping center. I just came from the one on J. Clyde Morris, but they don't have a ghost knife. I'm looking for a pair of Ram Cichlids myself.

There's also a place on Lynnhaven Pkwy, but I haven't made the trip out there to check it out. They specialize in aquariums and tropical fish unlike most pet stores around here.
