no smaller than a 10 gallon glass tank, is preferable. A glass or plexiglass lid is also preferable, to keep proper temperature and humidity.
Temperature: 74-78 degrees F (thermostat)
Humidity: 70-80% relative (hygrometer)
Playsand, Forestbedding (Eco-Earth, Bed-a-Beast, etc). Moss and calcisand may also be added to the tank, however it is not recommended as a main substrate.
Commercial crab foods, Vegetables (favorites include-carrots, lettuce, parsley, spinach, and corn), Fruits (favorites include-coconut, mango, apples, grapes, and pears), Meats (seafood, silversides and chicken are favorites), Grains, Peanut butter, eggs, seeds, algae and seaveggies. Please see http://www.epicureanhermit.com for a list of other edible foods.
Purple pinchers need both fresh and salt water (dechlorinated, salt made with a good marine salt like Oceanic).
Turbo, pica/magpie, Sharks eye. Shells with circular openings are favorites
