Thanks Mike.
Nascar fan.... Adult motoros should have a tank at least 3 feet wide (4 feet is much better) and 6 feet long. This guy is small and would be fine in a 2 foot wide tank. He is two years old and relatively small. If he stays small, which is possible, he'd be fine staying in the 2 foot wide tank. There's no way to tell for sure yet, as he could have a growth spurt and require something bigger in the future.
