Veggie only Tang/fish

[Bela N]

I managed to get some Caulerpa into my softy tank. I have tried hand picking, but to no avail. I can not get rid of the stuff. Purchased a Sailfin Tang (Z. veliferum), though he occasionally pics at the algae he tends to wait till I feed brine shrimp and them pigs out.

Are there any tangs which only eat macro algae, in particular Caulerpa??
Any other suggestions?

Thanks

Not a tang but by far the best macro eating fish I can think of is a Foxface/Rabbitfish. I don't know for certain on Caulerpa but mine ate every thing in my tank,even eventually mowed down some very tough red algae I had.
