size is measured from leg tip to opposite leg tip in a relaxed position, not the body. My LP is maybe a 1/2" now, in moist substrate, has a 1 litre bottle cap for a water dish, and i used the end of the paint brush to start a burrow in the corner of the enclosure for him. Now he's burrowed all the way to the bottom and is the monster in the dark when the roaches venture down there I don't mist his enclosure, just over flow the water dish every few days.
