Scientific name – Assorted species Family – Stomatopods Common name – Depends on the individual species Max Size – Depends on the individual species Care Level – Moderate Temperament – Aggressive Foods and feeding Smashers – They require at least on hard shelled prey item per month. Feed 2-3 times per week with meaty foods. Vary the diet as much as possible Spearer – feed 2 -3 times per week meaty foods. Vary the diet as much as possible. Supplements - Calcium, Magnesium, Iodine, Trace Elements Aquarium suitability - Reef compatibility – With caution, will eat snails, shrimp and crabs, and small fish. It may also move corals around. Captive care – The mantis shrimp will do better in their own tank. Most will be fine in 5 – 10 gallon tank, but a larger footprint is better than depth. The Peacocks will need a larger tank, 30+ gallons. Only one mantis shrimp per tank. They don’t like bright lights, and it can cause shell rot in some species. Smashers need large pieces of rock and coral rubble to build a burrow with. For all types of mantis shrimp, the rock must be placed on the glass and not the sand. They will burrow around and cause rockslides if the rock is not secure. Most mantis shrimp that hitch hike in are smashers. All mantis shrimp have appendages called Dactyles, and they can hurt you! Use caution when putting your hands in the tank. It is true that they can break glass, but this is EXREMELY rare. Only 3 species ("peacock", G. chiragra, O. japonicus) are capable of doing so, and they must be bigger than 4 inches. They must also hit the glass in the exact the right way to do so. Like all invertebrates, they are extremely sensitive to nitrates and copper, and should only be kept in aquariums with pristine water conditions.
