I have one LTA in my 30gal. tank and I'm considering to purchasing some SPS and LPS for my tank. I know that both species have toxic defense mechanisms that might harm or maybe kill one antoher. My question: What are the chances that my 3inches wide anemone will kill the corals if its tenticals were to touch the corals? The LFS suggested that I shouldn't add any corals with an anemone in the tank. Any other opinions will help.
