For sure the two emerald crabs I have do not touch the large-marble-sized valonia I get in my tank, which I have to remove manually every week or two.
BUT, I don't seem to ever see any "small" valonia patches which I get in my other tanks ... so ... whether this is just coincidence, or the crabs actually doing their job, I can't say, but it seems plausible enough to me that they might have an effect.
