Hello there! Long time lurker and first time posting, I found these two long white worms in my tank and was wondering if they're harmful or harmless. They're about 5/6 inches long and after looking through the ID threads I couldn't figure out what these were.
some tank details, 10 gallon has been up for about a month and a half now, last new additions were fish two weeks ago, and I used mostly dry rock with a piece of lr from the lfs to start it up
