Macro Eaters fish for 30 gallon tank

[snwmnky007]

So I have a 40 breeder top reef and a 30 bottom displayed fuge. In the fuge I have a ton of feather calerpa and cheato.

What is the best fish to eat the macro algae? again its a 30 gallon has about 40lbs LR, 1 scooter blennie, 1 rainford gobie, hermit crabs and snails.

I could only think of the Rainford Goby as far as fish, sorry.
