According to everything I read about them, they will eat other inhabitants.

Ive only seen them in species tanks around here.

Typically they are food until large enough to kill

This aggression goes both ways. Fish can harass and even injure an octopus. Use caution

Temperature needs are too different for an octo with 2 tangs...

What there are so many dwarf octos in the hobby from all over the world some like it in the 50s others in the upper 70s

So it's easier to get tropical octopuses now?

I've read of a guy putting four small octos, not sure of the species, kept in a fully stocked reef tank. When small they got along fine and didn't bother any of the fish or each other, but as they grew the larger octo picked off the smaller ones. Long story short, the octopus decimated the tank, killing every fish, if memory serves me correct 14 fish.

I believe that when certain species of octos, especially after feeding get harassed by fish or something else they will grab and kill what ever bothers them and just discard the item. Here's how I came to that conclusion: I would put five striped shoreline crabs in the tank, and my octopus would grab two or three and eat them up. He would finish them and spit out all the pieces of exoskeleton. The next day I would find the remaining crabs dead fully intact. I thought this was weird, so I decided to try an experiment. I fed my octo a raw shrimp that was too big to finish, so I would be sure that he would eat his fill. After about an hour I put a shoreline crab in the tank. He would push it away with his arms or use his siphon. After a couple attempts to push it away he grabbed it, held and killed it then released it once it died.

quick story, my daughter went to mexico for her sr. trip. While snorkeling she picked up an empty conch shell. She thought would look good in our aquarium at home. Said she had been carrying it around for about 30 minutes on the boat when an octopus crawled out. Needless to say, after much excitement the octopus and shell went directly back in the water...... Can't you just imagine an octopus crawing out with a boat load of high school grads, mostly girls.... :-)

when I tried this, my octopus ate most of the fish in my tank. one expensive octopus.

OK, so no octo with fish. How about corals?

they are fine with non stingng coral like sps zoos shrooms but not elegance or anenomes but all coral should be glued down

Don't forget the octopus may decide to redecorate a little for ya.. So nothing you would be heart broken if it got destroyed.

With my different octopuses, I have kept small fish with them... Sort of for entertainment for the octopus. Firefish and green chromis don't seem to bother them at all, and the octopus have never killed or attempted to kill (to my knowledge) their tankmates. This has been done with a bimac, wunderpuss, blue ringed and mimics. With larger species, I've never bothered to throw in any fish....
