grape cualerpa

[Ray Laneville]

Hi,
I've got some grape cualerpa starting to take hold in a 50g cube tank. I need to find something to eat it. I've heard foxface and some tangs, but I think they would quickly outgrow the tank. I've also got a 90g tank and another 90g I'll be setting up, so the fish could be moved. However I'm hesitant to add such a fish to the 50 because catching a fish hiding in the rocks is nearly impossible. I've also heard long spined urchins will eat it. Any suggestions?

Emerald Crabs, Sea Hares, Tangs, Angels, Urchins, some Turbos, Chitons, Limpets, and the Longnose Decorator Crab will all eat it this and other species of Caulerpa.
