I worked Veterinary before as well. Personal preference and belief is fine. But sometimes you just have to go by what is right for the animal. Case in point.... my cat who is extremely allergic to humans. She's stuck with us regardless.
This is a species that typically likes to hole up in termite mounds in the wild. While most of mine would be fine with a good size vision cage as adults. I currently have one very defensive hatchling that did the same thing as yours in a 10 gallon that is now perfectly tame in a tub. Once she's a bit older, we're going to re-evaluate and see about moving her out. My eldest female is extremely defensive and will constantly strike at the glass, she cannot be in an enclosure with a glass wall for her own safety.
I'd love to be able to have that girl in a vision, lol. But then I'd have a lot of nose rub and stress related illness with her. lol
