Yea I have the same thought. Last nite was the the first of it really, but it went on forever. I kept getting up thinking they were fighting, but most of the time they were not even near each other. Just crabbing and hissing,but this morning it started up again and they were wrestling around with each other.I ended up taking out one and caring him in a pouch for a while.So if any one has any advice on what going on that would be nice.
