LOL I just changed the water in all three of my tanks and I was thinking the same thing. Each of my fish had a huge bubble nest in their tank. The one who is in a half gallon actually had two and they covered nearly half the surface of the water. He's a really happy guy considering that he doesn't have a real tank or even plants yet.
