Best fish for hair algae control in a macroalgae tank

[Cthulukelele]

Hi so I have a 45 gallon sunlit t5 tank with macros, and I was wondering what fish would be good for hair algae control that wouldn't eat macros. I was thinking maybe a lawnmower blenny?

Since it's a full sun tank, the hair algae is more of a lighting issue than a nutrient issue. I am fine with a little hair algae. Just was looking for something to help out.

Lawnmower may go after some macros. Hit or miss. Should do well against hair algae.
