algea eater

New question which surgeon fish is best at eating algae off the rocks in the aquarium any recommendations ?

I am looking for a fish to replace my dwarf angel. I have a 35 gallon tank. Inhabitants are valentini puffer, 2 blackstorm clownfish, snails, hermit crabs, emerald crabs, & orchid dotty back. My orchid dotty back killed my angel. All fish had a semi aggressive temperament. I never had to clean...
