Barnacles causing hammer to be closed!
 

Well my hammer coral came with two barnacles initially. Since yesterday, I was noticing that my hammer is not opening fully and today, I noticed that there are like 4 or 5 barnacle openings and filters feathers are coming out and going in. What should I do?

When I had a barnicle on 2 of my frogspawn frags annoying them, I just plucked the frogspawn out before lights went on, so it was all retracted, then just glued the barnicle's shut.

So it happens. I was looking around the net but people never reported that barnacle's doesn't irritate coral so I was a bit confused.

Thanks for the heads up. I will execute lock down tomorrow :)
