So I am new to reefing. I finally got my levels under control after 5.5 weeks of start up. So I figured I would try a couple zoa frags to see how they and I did. Heard they were a good starter coral. I go to dinner then come back and a hermit is on top of one. I about choked. I think it was eating the algae on the frag base. it was green hair algae. Are hermits a danger? everything I read says not to worry. What do you guys think?
