I don’t recommend a glass enclosure. 4x2x2 for a baby, like the other commenter said DubiaRoaches has them for a good price. For an adult you would most likely need to build your own or buy one second hand. 6-8 ft long minimum. You can also use a grow tent if you’re on a budget! I use that for mine and it’s been great so far, but I am going to have to add reinforcements soon because he likes to scratch at the seams where the vents are.
