What is in my tank? I was doing a water change and cleaning the substructure and saw tons of very small white wigging worms. I has a 240 gal stingray tank with 1 23 silver aro , 12 ½ male motoro. I do NOT feed live food. All water parameters stable. I do use well water. How can I get rid of the white worms? Your help will be VERY much appreciated. THANK YOU.
