Mythrax are fans of it if they happen to come across it during their travels across the aquarium. They won't actually look for it and just because they may come across it doesn't mean they will devour it either...kinda hit or miss depending on that particular crab.
They should come off pretty easy, trying not to pop the bubble, by using your fingers to dig under the larger bubbles and manipulate them off the rock or rubbing the sides of the smaller bubbles so they can be dislodged.
I have had good success by using a combination of the techniques mentioned here. I keep 4-8 mithrax crabs, and pick out the bigger bubbles. The crabs won't eat those, and the small bubbles are too difficult to pick out. Great teamwork!
I always see my arrow crabs eating bubble algae. It is always fun to watch them if theres one floating around the tank. They are not the most agile of critters but they are determined. They always seem to prevail.

sorry, i just have to chime in here, too. i found that weeding them out by hand helped the most with the big ones. for the smaller ones, i got an emerald crab. he does a great job.
