Okay, let me preface the following questions by saying I have no idea what I am doing. Now that that's out of the way.. From what I gather from this website putting two octos in a tank together is a no-no. Is there any other creature I can stick in a tank with an octo? Do they just attack everything in the tank? I would like to put SOMETHING in there besides the octo. When I put live rock in there and the creatures emerge from the rock with my octo in the tank then what? Panic?
