i discovered a fuzzy red thing burrowing on the base of my xenia. Im not sure exactly what it is but every time my clown swims past it, it shoots back into the xenia. my xenia was the first coral i had and its been over 2 months since i had it and it seems to be doing well. is there some kind of dip i can do to get rid of it? should i even do a dip? please help!!
