They are like oval/circular shape. I haven't seen them move but, I'm finding them in other parts of the tank. I believe it was started from a stalk from a trumpet coral. I bought it really cheap and the water quality at the new store wasn't great. I think... No tentacles or stalks. Is there...
I have white oval dots approx. 1 centimeter. The are flat and stick to the glass & rock. I believe they came in from a stalk on a trumpet coral. They are now multiplying. Please help with identifying and/or eradicating.
