Cage an Octopus ?

So, you’ve got this pet octopus. Let me guess, she keeps trying to escape. Opening the lid to her tank, pushing the lid, creeping across the floor. You always manage to catch her before she squeezes herself down the bathtub drain. Sounds like you need a quick lesson in octopus husbandry.

By the way, you are not alone. Several months ago, an octopus named Inky escaped from the National Aquarium in New Zealand (he was eventually found at a nearby offshore reef and brought back). In that case, someone had accidentally left the tank’s lid ajar, so Inky made a break for it. But wait, if octopi—pardon, I mean octopuses—are smart enough to make like Andy Dufresne, should you be locking them up in the first place ?
