I was looking at my Cynarina and I noticed its getting duller and duller. It almost looks as though all the white in covered in brown algae. I did some reading and came up with brown jelly infection. I read it could be caused by damage to the coral, and this makes sense as one of my other corals fell a few weeks ago and punched two holes in the cynarina. They closed up overnight, but now this. All my other corals are fine, so I really believe this is what happened. My question of course is, how do you all think I should take care of this?
