I think this will be fine for an adult bp size wise. Still may need to cover 3 sides for added security and I DO NOT like the heat lamp hanging in the tank, I don't think that has to be there though. Not too sure about the vented corners either, that could cause issues with heat and humidity. If it were me I would choose a regular 20L over this, only advantage with this is they are stackable.
