This coral was grown from a small fragment and within 30 hrs this is what happened I'm not sure why? I did pull a pest anemone Thalassianthus aster, I tore the tissue of it and fluid leaked out into the tank. I don't know if they are toxic. That is the onlt thing I can think of the tank is stable otherwise. My next question would be what are the little oblong specs snail crap ?
