My tank has been running fine for a number of years. I have not introduced any fish or coral for a long time. But for some reason, my yellow tang and purple tang have both got black pin head sized spots on their body. I think this could be Turbellarian Worms. I can't get photo to show you as they won't stay still for a photo.
Can someone tell me if I am correct in thinking this is Turbellarian Worms? Also how on earth could it appear in my tank? And what should I do to cure them?
