Thank you very much! Great questions, I've been wondering myself. He's been doing so well I honestly haven't tried to weigh him this past year. As for length, I would definitely say he is now somewhere between 4 and 5 feet including his tail. Feeding him today, I'll get him near a tape measure this week!
The tub is a 62 qt. It's worked up to this point but he's ready for bigger and I'm thinking about what size his permanent enclosure should be.
