[header] How to care for emperor scorpions [title] House your scorpion in a terrarium or a fish tank. [step] The tank can be made of either glass or plastic, but needs to be sturdy and well-ventilated, and should have a secure lid that latches shut. Emperor scorpions are strong and can lift a lid if it's not secured. 
The tank should not be smaller than 10 gallons. If you plan to ever have two or three emperor scorpions in the same tank, opt for a tank that's 15 or 20 gallons.
