Bubble algae=emerald crab?

[MikeP]

Yeah, I guess it's better to try it out in my small tank anyway, I'd hate to try and retrieve a crab out of my 190g when I get it set up. I have heard lots of mixed results with emerald crabs but at least in the small tank it would be relatively easy to get a trouble maker out.

Thanks Tony

The emerald crabs I have seen lately go savage on valonia.

I have a 30 at work that the Valonia was getting out of control in. I picked up 2 Emeralds 2 and a half weeks ago from Neil and now I can't find a single bubble.
