Why the noise

[Brisch]

Every night after lights out I hear my synodontis eupterus and/or my synodontis njassae make noise like its screaming. Im just wondering if this is normal or if maybe the 4 of them are fighting and I should be worried. All are around 5" and there is 2 of each

put a dark blue bulb over the tanks so you can see what is going on.

If you have a vidio function on your cell phone or camera set it to tape for a while.

I guess that's why they call them "cats".
