ok well its almost a year now my 90 is been up and running and besides the flatworms all is well but i noticed my tiny little copepods are not so apparent and seem to of been replaced by stringy worm like things that are usually clear or sometimes red, they dwell in my sand bed and you can see them all over clinging to rocks and stuff all day, its most unsightly, so my question is what is it and where can i find more info
