Anemone gone missing

[docklink]

When I received the second shipment a month or so back, I received a Condylactis anemone with it. It almost immediately parked itself under a major ledge I have in the rock work and pretty much stayed there for 2 weeks attached to the rock, "blossoming" out through some openings in the rock during lights on. About 2 weeks ago it moved out from under the ledge and went behind the rock work to an area that gave it fair water movement and good light exposure and seemed to park on the sand there, still shrinking at night and expanding during the day. I fed it a pea size chunk of shrimp or squid every two to three days which it ate readily and it performed its "other functions" normally.
I left for a six day trip with a trusted neighbor coming in twice a day to top off the water (among other things). She is competent and observant and didn't notice any changes in the water clarity or condition of the aquarium. She last remembered seeing the anemone on Friday and I returned Monday night. Since returning there has been absolutely no sign of the anemone anywhere in the rock work and no sign or indication of any ammonia spike or change in the condition of the aquarium.
Question (finally ): Could the anemone up and die without clouding the water or otherwise leaving any trace? I've moved rock and looked every where and there is no sign what so ever. Even when it had shrunk to its smallest, the thing was about the size of a lemon and fairly easy to spot and it never stayed shrunk more than a day.
TIA for any thoughts or experiences to solve the mystery.

PS The kicker for me is that an acquaintance gave us a porcelain crab (different species from the hitchhikers in the rock) that moved into the anemone almost immediately and never left it, expanded or shrunk. The crab showed up on the rockwork yesterday, by itself, obviously.

Jeff,

Your serpent stars will make very short work of a dead anemone. Our condy decided to walk into a powerhead intake (screened, mind you) and died. In less than a day, it had completely disappeared--and our serpent stars seemed to be bigger...

Thanks, Hy. That would make sense to me. Both serpent stars are very aggressive when it comes to "eats" and the largest has (since the Condy disappeared) taken to hanging out at the end of the aquarium where the anemone stayed. It never strayed to that end previously.

Thoughts of that had passed my mind but she really is above reproach and has no way of keeping it.

Ever showed back up?

Never did. I've a BTA on order. We will see what happens with it.
