Mantis Shrimp (Stomatopods) have great personalities, are very intelligent and are beautifully colored.The Peacock Mantis is a "Smashing" Mantis and an extremely aggressive shrimp that should be housed alone. It is recommend that you keep "Smashers" in an acrylic tank, as a fully grown Mantis Shrimp has been noted of being able to crack glass walls of most aquariums.
