Clowns can actually cause tissue damage on many LPS
so they can negatively affect the colony. Not saying this will happen, but it can. Clowns dont always have a positive symbiotic relationship with its host. The problem comes from the clown vigorously rubbing the coral and in the case of Lps
like frogspawn they can beat the tissue against the sharp skeleton causing tears.
Not much you do just let things play out and see what happens long term.
