I don’t have big long clumps of HA though, just small patches here & there. He scrapes rock clean, leaving a white trail

I'm impressed with your ability to keep things alive for so long. I would hope it would eat the hair algae. I have a yellow tang that ignores it so I don't want more things that won't touch it.

I will probably take you up on that. I need to get my nitrates down a bit first. They are at 15-20ppm and from a quick google about them it seems they can be sensitive to nitrates.
