What is amazing to me is how quiet the tank is. You could only hear the noise I make with the camera. I'm also a little freaked out that they can see what is going on outside the tank perfectly. I wonder what they think of us... as really big fish that live on the other side of the river or do they not see us as fish but as a food source. I wonder what they think of my 5 year old and 9 year old bothering each other and running around the house screaming "MOM! He's bothering MEEEEE"
