Hi, all. I've recently begun doing octopus research, and the wonderful Shane Anderson at the UC Santa Barbara marine biology labs has allowed me to use his tanks to house my organisms. I couldn't help but be impressed by the octo-escape-proof tank that he'd created, and he said I could post images of it for all to see. I put it up here and not in the "tank owner's database" because it's a flow-through tank using seawater, and so it's just got a water input, an overflow outlet, and an oxygen bubbler. All the stuff about specific density and ph and all that doesn't apply. So here, if I did this correctly, is an example of a secure tank that doesn't use bricks! Any questions, want more details, just ask.
