I have heard over and over again that the best octopus for the home aquarium is the bimac, octopus bimaclodes.
As far as easy and low maintenance, as long as you have an octopus, that's not going to happen.
I would recommend urchins. You have to have the water in good condition and with algae, but they are really easy and people love them, because they bumble around the tank when you least expect them to.
With urchins I would recommend clowns or cardinals, because they won't interact.
