Algae eating fish for a Sps tank

[trueblackpercula]

Hi I have a 120 cube and need to add a fish that eats algae and won't eat my Sps. Can everyone share what they would add if they had a tank of my size of 30 x 30 x 31 deep.

If you you have a special type of goby , blenny, tang, Etc please post a picture so I can see my choices.
Many thanks

rabbitfish are great for sps tanks.

All kind of surgeon fish, a good algae eating fish is a Zebrasoma Flavescens.
Also a lawnmoyer blenny is great, it's a quite funny fish though...
