NC Frank- Don't take this the wrong way, but do you sit within a few feet of your aquarium on a daily basis? I ask because, being unemployed/college student and the way I have things set up, I sit in very close proximity to my tank for a majority of every day, the tank less than 3 feet from me. I suspect you haven't heard it if you have a more normal setup than I do hahaha. It would be easy to miss with ambient noise if I were further away, but as I have said...I have 3 others who have seen and heard this behavior with my fish so I don't think I'm completely crazy. A little, sure...but not totally.
I started keeping my own angels when I was 13 (24 years ago) and my father kept them since before I was born. I used to sleep about 3 feet from my favorite angel trio from the time I was 13 until I was in college (black, pearl scale and white yellow marble - had them from quarter size to full grown monsters). I can feed my current angels by hand, pet them, etc. I used to breed angels also. Never heard one make noise. I am not saying that it isn't possible... because nothing surprises me in this hobby. I just find it hard to believe that they could make a noise loud enough for you to hear through the water/glass and above even the most quiet filtration systems with minimal ambient noise. I also do my best to not make my angels agitated.
