Yeah. I just choose a sailfin tang to clean up a new tank. He's in hog heaven but he can't quite keep up. I might have to get him an urchin to help. My urchins in the other tanks scrape lots of coraline but don't discriminate. They leave a clean path as they travel. Good luck with it. You'll find a predator for your algea.Tangs would eat that like candy
