Please ID these hitch hikers
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! Last edited by Zoidberg; 03-18-2011 at 05:20 AM. Reason: spelling |

1. Seriously bleached mushroom (Actinodiscus sp.)
2. No freaking clue... almost looks like two sea cucs goin' at it. Can you desribe it a bit? 3. Looks like a snail of sorts. Nassarius maybe? Got a better pic? |

Thanks ScubaSteve,
#2 doesn't move very often. I'm pretty sure it's just one critter. I've seen it in a few different places on that rock and it's always sitting there not doing much. #3 is tricky to photograph right now. I watched it for a while and the other side looks like some sort of clam. It's got bilateral symmetry and pulls itself along with a foot/tongue. |

Better pictures of #3
Sorta bad focus on this one but it shows the foot. |

Is your number #2 hard?.... Ok, that sounds weird... Feels kinda like I'm playing a dirty version of "Guess Who?". Does it move around? Does it keep the same shape as it moves around?
#3... that things cool. I still can't quite tell. It's a bivalve. Based on the shell shape and the hinge I say a clam of some sort. But what blows my mind is that you say it pulls itself around? |

I think I had a few #3's in my tank but they were much smaller......try googling Cantharus Whelk.....or Columbellid snails (aka Dove Snails).....both are undesirable hitchikers so I removed mine just to be sure.
