devonmessick Posted July 11, 2016 Share Posted July 11, 2016 Hey! I am only about 6 months into my first salt water tank. I noticed something growing on one of my rocks. I feel like it came out of no where. It is a white worm like thing with something growing out the end of it. Is this something I should be worried about? I have no added anything new into my tank in over 3 months except for using live water when I do water changes every other week. I have attached a photo. It looks like it has popped up in a few different places. I have circled what I am talking about. Thanks in advance!!! Devon Link to comment
