What’s Making That Awful Racket? Surprisingly, It May Be Fish

[naiad]

Interesting. My pet fish make a variety of sounds, it is just difficult to hear them from above the surface and with background noise. I have some underwater videos of them in which they are making a metallic chirping sound. Very rarely they grind their teeth, which is clearly audible from above the surface.
