I had to chuckle about this one!! What I'm going to say is true but probably coincidence.
I bought a pair of bonded clowns and bought a large anemone (see photo) a week later. When I stuck the anemone in, I had Beethoven's 9th symphony (the scherzo that was used in that movie) playing at an insane volume. The clowns took to it immediately and after a couple of months started laying eggs (a hatch is due tomorrow night) behind the tentacles edge on a huge LR. You can see little silver eyes in the attached. Today is day 7. They always hatch on day 8. Next time I'm probably using a tile (or I'll fork out for a proper trap) and transferring to a breeding tank if I really feel like raising fry. I have enough work to do with this 1200 litre set up as it is and I ain't young anymore.
I find it interesting (and somewhat amusing under these circumstances) that I'm a musician/composer/pianist with something classical playing all the time when I'm not at the piano. I always wonder if the musical vibrations affect my fish. They are all so healthy and they get along beautifully - a bit unlike that poor man in clockwork orange stuck in a room with a 20 inch speaker under his floor!!
