Question- my colony or mushrooms have these strange white things that look like either worms or tentacles. They range from about 1/4 of an inch to one inch in length and were spotted in clusters coming out of the mouths of the polyps. This is the first time I've ever seen them since I bought the colony several months ago. I can't get a pic- sorry- and am willing to be as descriptive as possible if that helps. This sound familiar to anybody? Are these things harmful? Can I get rid of them if they are? Thanks for the info!
