The mantis shrimp has to be one of the most dreaded of all uninvited animals to discover in a reef tank. As soon as a clicking noise is heard the reef aquarist's heart jumps into their throat. "Is it a mantis shrimp? What am I going to do? How am I going to get it out of there before it eats all of my fish and shrimps?!" Mantis shrimp are also misunderstood, and not a lot of information is being circulated in the reef keeping hobby about them other than the fact they are undesirable in a mixed invertebrate and fish aquarium.
