I just finished up successful removal. I used tweezers and removed one by one in the tank. I also got 2 emerald crabs. At first I was concerned about popping bubbles, but I noticed that the emerald crabs pop the bubbles when they eat them. So I continued to do a total removal with tweezers, and yeah, a bunch popped, even when I was careful. But now that I got the mega infestation cleared, the crabs keeps anything else that may crop up at bay.
