Does anyone have any experience with Spanish Dancer Nudibranch before? Some said it eats only sponge. Other said it eats coral and anemone. Some said it can sting and kill your corals and fish. Which is true? I have only LPS (cynarina, flower pot, sun coral, torch, frogspawn), a few bubble tip anemones, clown fish, starfish, gorgonian, will the Spanish Dancer sting, kill or eat any of them? Your experience is truly appreciated.
