Me too, andysgirl. I have about six of them on one rock and haven't had the courage to pick them off yet. I always wonder how the emerald crabs eliminate them without popping them. Anyone know how this works?
The bubbles are harder than you would think. I wait until they grow a while before grabbing them off. My crabs are too busy sitting around to get to them.
Hahaha. Yeah that's how mine are too. When I first saw a few bubbles, I tossed in half a dozen emerald crabs. I see those guys everywhere EXCEPT where the bubble algae is, busilly picking on rocks that have nothing on them.
