Green Mantis Shrimp

Mantis shrimp are very aggressive and are usually reserved for a species only tank.  I would not recommend mixing them with any other fish, shrimp, crab, or thin-shelled snail.  I would also not recommend handling them, they are called thumb splitters for a good reason.  For more information on mantis shrimp, go to Dr. Roy Caldwell’s excellent site dedicated exclusively to mantis shrimp.
