After fitting a water bowl, and a hide in there, I find there just isn't much room in a ten. Tens are easier to find space for in the room, however. I've got a king in each of two tens currently. Since neither is quite as long as the tank, they are staying for now.
The new corn, however, is approx. 33 inches long, and is in a 30 inch long tank. I do NOT like that! A new tank has been shipped, so I'll probably have a better set-up for him in about a week.
