The Rainbow Fish, by Marcus Pfister

The Rainbow Fish with its iridescent scales is the most beautiful fish in the whole ocean. But since he is also vain and proud, he becomes more and more lonely over time. Then he realizes that you can't win friends through beauty. He overcomes his pride and begins to distribute his glitter scales to the other fish. https://podcasters.spotify.com/pod/show/letsreadlylaanddad/subscribe
