Joe and anyone else itnerested in FW inverts, Aqualog has come out with a new hardcover "special" called "Shrimps, Crayfishes, and Crabs in the Freshwater Aquarium". Like most of the "specials" it includes a nice poster with 64 photos of different inverts on it. It contains more information on more species than I've ever seen anywhere else.
