I did keep a bimac, Ollie, but she died about 6 weeks ago. So I'm between octopuses, and intend to get another bimac, but not in the near future.
Right now I have a small invertebrate tank with a very friendly cleaner shrimp (skunk shrimp) who comes whenever he sees either of us. Also hermit crabs, snails, big featherduster, strange mushroom anemone, etc.
