This was probably the most interesting fish related video I have ever watched. I have had multiple filterless tanks. There's a thread on a historical tank, I can't remember whose... anyway it doesn't even have air. I tried the no airstones.... and I also feed mosquito algae in the summer. Let's just say my filterless tank has airstones now. If you want more information, The Treatise on the Planted Aquarium by Dr Diana Walstad may interest you.
