Came back from few days vacation and have noticed Black Encrusting Sponge ( I suppose) on base of my Hammerhead. This particular colony seem to be a bit less extended, although no really big difference. Could it be Terpios hoshinota? If so, should I get rid of this colony? I can banish my coral to a "special" dungeon aquarium with other pests ( majano, mantis shrimp).
