Never, ever, ever, ever had one stress out in glass. I mean never. Ever. (Ever)When you keep a box turtle in a glass enclosure they stress out. If you have to use glass or anything clear, you should try to put up paper or anything that won't allow them to see outside the tank. it should be high enough they cannot see out. The larger rubbermaid bins are good, bc they are about $20 for a 55 gallon, and that is a decent size, if you have to keep her in the house. Plus the 55 gallon tubs can be dragged outside when it's nice and set in the shade. ( as long as your yard is safe from dogs and predators at the time.
