Herbivorous fish suggestions, help.

[speedstar]

I would usually just have some tangs atleast a scopas to pick off the algae on the rocks, but my return to reefing has me using a small IM-40. What is a good fish to add in a small tank that eats like the tang would have helping clean the rockwork.

Thanks

Blennys

Midas blennys are entertaining to watch

Prior to eating the big stuff, I would think that snails would be the first herbivores to get. Once the nuisance algae progression starts, consider an interesting herbivore, lettuce nudibranch.

Yes to blennies. Get either one of these two, but wait for algae to be prevalent.
