Anyone have success...

[OCDP]

With emerald crabs eating small Bubble Algae? I have more than I'd like from a zoo frag I got from a local reefer...(bob) and now my tank is full of bubble algae And I would like to get rid of it before it spreads to every single rock....Unfortunately the BA is not easy to reach and I would prefer to not have to move anything around in my tank to remove it, as everything is finally stable and mature in my tank. And I don't want to have to disrupt anything.. So I am just getting a feel of how many people have or have not had success with emerald crabs.

TIA,
Scott
