Mantis Shrimp
Details
Scientific Name: stomatopod
Identification: a marine crustacean that can grow up to 10 inches in length, these shrimp hold their front (club-shaped) appendages in a way that resembles the terrestrial "praying mantis"
Pest Management
Treatment: Groupers, Triggers, Eels, and Snappers eat mantis shrimp; you can also set up a trap to catch them - these shrimp are notoriously hard to catch, and live in burrows in the tank
Prevention: Carefully examine, clean, and then quarantine all rock and coral before placing in the tank. The shrimp like to hide in holes and burrows
