squeaking fish

[sm51498]

I have a Dascyllus aruanus that makes funny little squeaking noises when he is chasing other fish around. Anyone else have noisy fish? Anyone else experienced this kind of behavior with this particular fish?

Yup, Heniochus, they make what can only be described as a clicking sound. It's really weird and almost inaudible through 3/4" acrylic, kind of sounds like it's coming from inside your ear.

There was an article linked to a thread recently about
the communication of various clowns through "clicking"
here on RC recently, but I'm not sure how to find it.

Emperor angels grunt.

My tusk has been making some sort of audible noise when he chases a tank mate lately. It's weird because I don't think they're supposed to make noises. I thought I was imagining it for the longest time, but when he did it in front of my mom, she asked, "Did you just hear that? I think it was your tusk." So it's not just me hearing it at least... The sound is hard to explain. It's like a really low, strong grunt.
