Can you identify these pictures?

I moved my live rock and cleaner shrimp into a 10 gallon quarantine tank since I am treating my display tank. After a few days, these things started showing up:
Picture 1: Green but clear bubble-like thing to the right of the feather duster in the middle of the picture, and a small colony of them right above it. Several smaller bubbles all over the rock. Size varies from about 1/32 to 1/8 inch in diameter.
Picture 2: Some kind of soft coral? About 1/2 inch in diameter. Pink, almost transparent, with white "dots" on the end of each "tentacle". One more of the same rock.
Picture 3: This one is attached to the front glass-wall of the tank, so the picture is taken from underneath it. About 1/2 inch long

1 is bubble algae. I would get an emerald crab and some peppermint shrimp to get rid of both of them.

1 is bubble algae, 2 appears to be a small coral polyp. These are common hitch hikers and not a problem. 3 is aiptasia.

2 - Carribean Mushroom, probably pseudocorynactis
3 - Aiptasia

Thanks alot all for quick replies!
Does anyone know how big the Aiptasia gets?

I've seen them at least 3" long, and they probably get bigger. The problem isn't their size, however, it's that they can reproduce quickly and take over a tank.

emerald crabs in my experience, does a very good job of eating bubble algae.

After discovering that two of the three unknown things in my tank were "pests", I found this comment (by someone explaining how to cure driftwood for a freshwater tank) extremely funny:
"If it was sitting in saltwater, there is unlikely to be anything harmful left on it besides the salt. Salt has a nasty tendency to dessicate anything alive."
