Caulerpa eating fish/CUC for a Nano?

[Rybren]

I have a 28G zoa tank that has a Caulerpa infestation. I added a small scribbled rabbitfish and it cleared out the caulerpa and BA, but the tank was too small for the fish, so it got moved to my 120G.

Fast forward a couple of months and the caulerpa is starting to return. Is there any fish or CUC that I could add that would likely nibble on the macro? I'd prefer a fish that wouldn't outgrow the tank.

Thanks!

There's a section for caulerpa and recommendations on CUC that eat it.
