Rob that's cool, we've had a dozen or so pepermint shrimp who wouldn't touch either. We brought something into the house last year that must have been laden with hidden aptasia and now because we move things from tank to tank to tank they are everywhere... manually nuking them seems to help, but it's getting old.

We played the same game with majano, but ultimately won that battle, (we found the source and haven't returned to that LFS) haven't seen one since last winter.

Guess it's a crap shoot as to what will predate on them and what won't...
Karen whatever you try please let us know how it turns out.
