Im still in the learning portion of the ceph world, and am setting up the stage for a Bimac. I however woud like to have as much interest in the tank as possible besides just the octo. my question. What can live with an octo. I have read anemone, pincushion, and LPS are bad, they have nasty stings that can damange a ceph. BUT, what about zoas? shrooms, xenia, GSP, pipeorgan etc? excuse my spelling,,, english was never my forte' FYI, I have a successful 150g (200g total sys) full reef with SPS, LPS, anemone, etc, I know what IM getting myself into :) thanks for the insight! I dont want to "burn" my new friends skin, but at the same time, I dont see how a few shrooms could hurt?
