Omnivorous fish for GHA (60L tank)

[Nanolifeuk]

So I have a very minute problem with GHA on my back wall. I am worried that it’s not a large amount so I would need a fish capable to control this and eat regular foods (mysis, pellets). Any suggestions- wrasse?
I would like a Blenny but I’m also cautious there’s not a lot of hiding spots and quite large gravel in this tank.

No wrasses eat algae (that would fit in this tank size). I would recommend looking into Koumansetta hectori if the gravel isn’t overly large.
