What eats grape caulerpa?

[Son Of Skyline]

I've had both a foxface and naso tang eat grape caulerpa. I had so much of the stuff I *almost* packed it in and gave up on reefing. These fish definitely keep it under control. I know the grape caulerpa is still there, but it never gets a chance to grow. I have a feeling that if my foxface ever died the caulerpa would come back.

Good luck!
