Aquarium Advice Freak
anyone ever get muscles in their live rock? I recently purchased a rock with many polyps on it. I also noticed a muscle attached to it. I figured it was just the shell and there wasn't any life in it. Once I got it home and acclimated the rock, I placed it in the DT. After about 20 minutes, I noticed it was open. I payed close attention to it for about 20 more minutes and noticed it snapped closed whenever a fish would pass closely. It's alive! I am shocked. I never would have known for them to survive in an aquarium environment. Does anyone know how to care for these things? Its pretty cool and I would like to see it live.
