So is there a list of soft corals/LPS corals that are a no-no when trying to get more into a more SPS dominated tank? Someone mentioned that Xenia could be harmful to SPS. Keep in mind, I am not talking about corals touching just simply being in the same tank or close proximity. Had I known what I know now, I would not have ever put Xenia in my tank. Luckily it's on a rock that is marked for removal during a re-landscape. Thanks in advance.
