Did u get another Kole tang or is that an old picture? And that looks like aptasia to me which is a bad. Kill it before it spreads or attacks. There is several ways of doing it can even do it with a laser if u want Google aptasia and see which way will work best for u.
I'm not that familiar with Aiptasia. Would you mind briefing me on it's function or possibly it's pathology?
