... no. Fish dont care. XD
I keep water level in one of my tanks low (6" from rim) because the fish require it, but in most of my tanks I keep it high and put an air stone/wand in there. Ironically, the one with the low level is 10' from where I sleep (same room), so I had to attatch some boxers to the front of the filter to keep noise down. Embarrassing? yes. Practical? Definately.
