Have a couple of these little green looking bubble sacks on one of my rocks. They have a hard shell it feels like. Just wondering what they might be.

Anyway to get rid of them?

Removing by hand does work if you can knock them off and suck them up it is pretty safe. A lot of people swear by Emerald crabs but I hardly have luck with anything that is supposed to eat something else. Vibrant is also an option but has gotten some really bad reviews lately.
