Foxface for hair algae with black back bfly?

[SteveCGY]

I had really bad really long hair algea everywhere. I used a long spined sea urchin and everything was spotless within 48hrs. Worth a shot if you can find one to borrow. After my tank was spotless i had to give mine to another member on here as he was much to large for my 55g tank.I also tryed the lawnmower blenny and it was useless. My hair algea was much to thick and long for it.
