i have 2..a flordia and a gator, both about the same size (14") and sometimes they like snuggle up with eachother when they lay on the gravel......precious i know.....they also seem to follow eachother around.
I agree keep them close in sise...although there was one instance when my gator gar had my short nose in his mouth for a bit, didnt last long i think the shortnose just got in the gators way. good luck
