I just bought an awesome zoanthid colonized rock and I proceeded to drop it on my green hammer, ugh....!! Some very small pieces (2 or 3) of the green tips of the tenticles were floating in my tank. The green hammer has since come back out for the most part. My questions are: 1. do i need to get those small pieces of tenticle out of my tank? 2. Will those pieces of tenticle possibly seed in my rock and grow? and 3. Is there anything I can do for my poor green hammer to ensure that he does not die due to the trauma? Thanks
