Beverly, even though it is an obvious point, I think that it's something that we need to keep reminding ourselves of.
The fish we keep normally squabble and fight in the ocean, and have no limits of where they can flee, the only limitation is their own size and speed.
IMO, fish that we sometimes call "carpet surfers" are simply fish that ran out of running space.

Also - if they can jump out of the tank while "fleeing", then it makes sense that they could also run into something like an open, waiting anemone. I'm pretty sure that they don't normally hang out in the ocean 10 or 12 inches from dangerous anemones.
