Yep. Fish have a bit of sense to avoid them, but just like people, fish can panic too. How many accidents out on the roadways wouldn't have happened, if the driver didn't panic, and over-correct, slam on the brakes, etc? Well, if something causes the fish to spook, slamming on the stand/canopy, TV coming on too loud, etc, in their attempt to dart to safety contact with a deadly anemone, is a real possibility.
