I've got a trachy that seems healthy but my clownfish decided they like sleeping in it. As an effect they caused the skeleton to poke through in a few areas they rub against often. That exposed few spots had started too grow some algae, rather than healing over, as I had hoped. Any ideas on how to get rid of algae and heal this coral. I was planning to put a bottle over it for a while to keep the clowns off it but happy to hear other suggestions. Should I do something to remove the algae? Thanks!
