Small fish for hair algae

[The_Barrs_Reef]

Hey everyone! I have a small frag tank in my sump on a somewhat newer tank and having a little hair algae showing on some grave and the rack and I’m trying to see if there are any small fish I could put down there to help with it, it’s a small area so obviously not any tangs, and trying to not put a clean up crew down there as they seem to keep getting into skimmer and other areas I don’t want them, (photo attached)

thanks in advance

In my experience there isn't any that really eat hair algae. May want to up the CuC and get it at short as you can.
