Haha interesting. I've experimented with a 40 gallon before. I'd say go for it.the mother to this little one digs all the time, shes always at it. im real tempted to put her in a 45 gallon i have and see what she will do with more room. could be interesting.
from what ive seen on post's and such they dont usually burrow alot as adults. so who knows.
ive decided to call the little one dozer.
