Any crabs that are just plain too slow to hurt fish? Don't have to be reef safe.

emeralds definitely attack fish.

I have had several emerald crabs over the years and they have never hurt a fish in my experience. They do eat a lot of algae and meatier stuff when they get bigger. Mine love krill.

I'm not chancing emerald crabs.

+1 to pom poms. Neat little critters. Very shy though! Have 2 in my 36 gal reef

Porcelain crabs and usually Pom Pom crabs are okay but stay away from Sally light foot crabs and emerald crabs.

Definitely steer clear of the arrow crabs as they are extremely aggressive. They are kinda cool to watch though.
