Guaranteed to eat caulerpa?

[Anonymous]

My younger son loves lettuce, while my older son never touches it. I think they share the same biological parent...

Do we need to beat a dead horse?

Ok, I don't need guaranteed, I just need "most likely".

I tried mithrax crabs, putting in 4 big ones. Within minutes they started munching on the caulerpa. Soon all my intakes were clogged with fragments, and I thought they were going to do the job. Within a couple of days all 4 moved to the caulerpa-free side of the tank where they eke out a living from the valonia there.

I think the evil red eyed crab (that I have only seen once) may live over on the caulerpa side and scared them away...

Considering a foxface. I like the uspi.

I'd also recommend trying Siganus uspi (Fiji Rabbitfish). While I haven't seen it eat caulerpa, IME, it devours anything green. In fact, it's the only fish I've ever seen eat bryopsis algae.

Naso Tangs will quite often go nuts for this stuff, from my experience with ones we have had or sold at the store.
