Grape caulerpa

[Xiaan42]

Right now one of my zoo frags in my tank is covered in grape caulerpa. besides removal by hand is there any thing (fish or crab) that will eat the stuff and keep it under control that will fit in my 38G tank? I know tangs eat the stuff but will a emerald crab or any other fish?

I think your best bet would just be manual removal. Anything you might add will just increase the bioload. Kinda like throwing fuel on a fire. Addition by subtraction.
