Well, I saw Banana starting to build a bubble nest when I got up one morning, and when I got home from school it was the size of a silver dollar! I was so proud of him. Of course it was on the side by my sister's female's tank, and he started a mini one by Fish's side, too.
I had to take it down when I changed his water, but he built a bigger one after that, but it broke when I fed him, his fins messed it up.
