I need a fish to eat macro algae and get along with mata

[LineSource]

I have a mata tang, about 5", a scooter blenny, and a mandarin goby in a 125g 6' tank.

I know the mata will outgrow the tank eventually, that sucks, he's a great fish.

I brought in some macro algae, I think caulerpa. I brought it in because I don't have enough rock in the tank yet. I figured it would help keep the water clean until I got another 100lbs of rock.

Problem is it grows really fast, and it's getting up in one of my corals. I trim it back when I do water changes, but it's a pain.

Is there a fish that will get along with my crabs, turbo snails, peppermint shrimp, and 3 fish.

I've heard the Mata is a mean fish, hard to imagine, he seems so sweet. He's usually dark, but brightens up for people, he almost glows.

Ah caulerpa. In my opinion there is NO WAY to totally clean it from a display tank, naturally or otherwise. I know people use it in refugia, but I would never take that risk. Good luck!!
