I just got my BP and he has lived in a 6QT tub his whole life on news paper I think. I put aspen in his 10 gal and he seems to love it. He roamed around his tank 1 time in the day and it was the first day I got him. The second he slept the whole day and he was moving around for like 10 minutes today then went back to bed. He is also only 7 weeks and a couple days old. But yes I would recommend aspen.
