Which inverts are Macro Algae safe?

[Northwest_Scapes_]

So I'm looking for a good cleanup crew for my upgraded Macro Algae / NPS dominate tank to kind of cleanup left food and detritus. I've had good success with Astrea's for hair algae and Nassarius for food in the sand so those are being carried over. I'm looking for some other inverts that could maybe get into smaller cracks in the rocks, would some stuff like dwarf hermits or ceriths would work?

Brittle stars, terebellid worms, eunicidae usually, all Amphinomidae I can think of, most amphipods
