New to R2R. What are these? I'd ask my lfs, but they are not the best with Q&A. I noticed these about a month ago and they have multiplied and grown. They are white ( now green with algee) worm like. I have not added anything in about a year and haven't seen them in either tank over the course of 3&5 years which is when I got in to this hobby.
Any help is appreciated.
