Advice on fish for algae control

[Perpetual Novice]

I have a 13 gallon tank full of zoanthids and some snails and hermits and a pistol shrimp goby pair. I’m looking to add a fish that is appropriate for a nano tank and will help reduce the algae. I wouldn’t say algae is a problem but snails don’t really seem to be doing anything about the hair algae slowly accumulating.

So far my best candidate is maybe a tail spot blenny. Anyone have any other suggestions?
