Turtles develop a regular schedule of sleeping, bathing, sunning and eating.
If they aren't housed outdoors, they need access to an area of soil in their enclosure so they can dig. Digging helps keep their nails shortened. Box turtles also like to bury themselves in leaves, so these can be provided in a corner of the pen. The habitat should be constructed so the turtle can climb in and out of the water easily. The water must be kept scrupulously clean.
