I would pick either a Kole Tang or a Tomini Tang (have one of these right now) for helping with cleanup. I desperately wanted to try a Scopas Tang but was not able to get one out of quarantine and finally gave up.
IME, the foxface we had did not help with hair or bubble algae cleanup. He was a pig for food I put in though and was a spaz that kept all the other fish on edge. Good riddance to that one... I have a very small bi-color foxface right now that does a little picking at the rocks but nothing noticeable.
I ended up getting a Halloween urchin that mowed down all the hair algae in a week... He is still cruising around many months later, but I am now worried he is not getting enough food! I have emerald crabs to help with the bubble algae.
