This is only my second post. I've had the majority of my questions answered by doing searches up until now. We've had our 80 gallon tank for 5 weeks now. It was a well established tank before we got it. My question is what is the weird stuff that grows under the rocks. It looks like its make up is of some sort of mushroom material. It has tenatcles extending from it like some sort of immobile anemone. Good, bad, harmless? My wife wants me to remove it. I've done searches but can't find any information on what it might be.
