So I have just recently gotten a 112 gallon saltwater tank and am completely new to keeping marine aquariums. I just recently noticed that I have some anemone looking thing growing on one of my rocks. Its hard to see in the photo, it has a pink base and clear bubble looking tips coming off of it. Its really small right now, about half the size of a penny. Any idea what it is? Also, I have a small pink tube looking thing on the same rock. Are these things dangerous and should they be removed?
