[Fish]

Hi all,
I'm a little frustrated with bubble algae growing on the rocks my zoanthids are on - I'm sure that blocks the zoos from spreading.
I have read before that emerald crabs will eat this stuff.
Does anyone know if this means "emerald crabs love eating bubble algae" or "I once saw an emerald crab eat bubble algae."
Just weighing the pros and cons; I know that crabs can become a problem themselves in an aquarium but I'll take the risk if they are likely to take care of this algae.

Thanks for your help.
