EXACTLY....had an acquaintance tell of a friend of his who owned an octopus. Had a fish tank next to the octopus tank...the guy worked nights. He would come home and find all of his fish gone....refill the tank, and then the fish would be gone. Set up a camera....turned out the octopus would climb out of its tank, crawl into the other one, eat the fish, then return to its tank!
LOL. Why, that slimy little cephalopod! Must have cost this guy a fortune to be replacing saltwater fish on a regular basis. Did he eventually wise up and put a sturdy lid on the octopus tank, or did he enjoy the octopus for dinner one night?
