I've kept my ball python togther with other snakes before with no issues, and these guys have been together since Jan. Their care requirements are similar enough, both molt just fine, plenty of hides are in the current cage, etc etc etc. This is the first time an issue has arisen, so while I was planning all along to move the Dums to his own cage eventually, I've decided to do it now.

Thanks for your concern. Dually noted. Back to the issue at hand please.
