He looks so pretty in blue & cream colors...but as far as activity, that's what's so cool about rat snakes in general...they have more than one speed.
Not that you're going to add any more snakes, but if you wanted a rat snake that moves like in this video (& FYI for others reading this) you should have
gotten a Trans Pecos rat snake...they are very chilled when handled, and even in their cages they are graceful & seem to "tiptoe" over their branches.
Plus they stay about 4', not longer than the biggest (or older) corns, but a little heavier-bodied...very stealthy & nocturnal, but nosy (easily interacted with).
(-just sayin'...I know, I'm a bad influence...lol.)
