Aptasia or other?!

[Pier Pressure]

Well I bought a single peppermint shrimp and the same thing happened - just went missing one day - no body or shell or anything. I never saw it again and thought maybe my big cleaner shrimp (I have two) took it out as they were charging the poor little guy when I put it in.

I then added two peppermints and though they do not show their little faces too often I know they are in there because they come out sometimes for feeding.
