For a while, I was really into fishkeeping and really wanted to get an octopus as a pet. They are supposedly really smart and quickly learn new tasks (like the opening of a jar).
The problem with having them in a small tank is that they are amazing escape artists and can slip through the smallest of holes. Also as a downer, they typically live only 12-18mos and they can't be bred in captivity, so I eventually gave up the idea.
