Please ID these hitch hikers

[Zoidberg]

My tank is just finishing cycling, and I've found quite a few hitch hikers in my live rock. Any help identifying them would be appreciated!

#1 some pink ricordea or mushroom coral? It curled up pretty tight when it was first introduced to the lights, it's still parked in the shade for now. about 1/2" across.


#2 no clue what this is, 3/4" across.



#3 Not sure what to make of this guy... I thought I only had one, but today I found 3. About 3/4" long.


Thanks for looking!
