Singing Fish to Deter Predators?

. . . and the eyes blink.

i think it is the element of surprise. Though i have read of people leaving radios on in their pens at night to deter predators. i would actually like to try a singing something, but only if i could buy it cheap at a Goodwill.

Oh wait, i just remembered i have some motion-activated Halloween decorations. One is a plaque with a skeleton whose head turns and he says "Good Evening". That will be perfect!

I'm afraid anything smarter than a skunk will get over it.
