Hello all. After a few year hiatus from keeping fish, I just put a deposit down on this 72 gallon corner tank that will house a octopus (or maybe a cuttlefish). I've kept saltwater fish for a long time but have never kept cephalopods. Knowing that I won't have an animal in the tank for 3-4 months, I want to setup the tank with a cephalopod in mind. There is a glass top on the tank that I plan on duct-taping down, and I think I'll use duct tape to cover plumbing holes (unless someone has a better idea). I'd like to keep some simple coral polyps as long as they won't hurt the ceph. Beyond that, I am just getting ready to put together this setup so any advice is appreciated. Thanks.
