Octopus for my Tank?

[gabew]

I was wondering if I could have an octopus in my 30g cold water tank
I know these guys need very good conditions so imagine my tank will be perfect. It is not fully built yet so I am still figuring out how it will work and how perfect it will be
Instead I have a few behavioral/feeding questions
I have heard that these guys will try to escape tanks, so how "sealed" does the tank have to be, do people mean don't leave to lid open or they the lid has to be air tight?
I want to have some shrimps fish crabs and other animals in the tank too will it eat everything (I want a small one), if you feed it enough will it be fine"? I don't mind if it eats a few animals every month i can get more from around here, it may even help to stabilize the populations, if it doesn't eat too much.
Finally what, how, and how often does it eat? Does it need live food or would frozen shrimp work? Like I asked above "if you feed it enough will it not eat everything else?" what if "feeding enough" every night twice a day once a week?
thank you

if i really want one looks like it will need its own tank, maybe leter

Good choice, they are especially fond of everything you listed to go in the tank with it, lol.

not only are they a fan of everything you listed, they can get bored easily= not good for tank mates.
