Valonia and Emerald Crabs

I've had several episodes of bubble algae in my tanks over the years and have always purchased Mithrax (Emerald) crabs to get rid of them. They seem to go after the smaller bubbles, however. I've actually watched them attack a patch of bubble algae and have it completely consumed in hours. Once the bubble algae is completely gone from the tank, you don't see the crabs any more. I am assuming they either hide in the rock work or die of starvation. I give the Emeralds a two thumbs up.

Good Luck!
