I have a 45 gal tank with several large angels & a couple of silver dollars. My girl friend was at a wedging shower over the weekend & she came home with one of the center pieces from one of the tables. It’s a small bowl with some type of floating plant on top & large gravel on the bottom & a male betta inside. I would like to put it in with the angles, But I’m not sure if it could bother the angles? I’m not to worried about the angles bothering the betta because theirs a lot of plants that the betta could hide in.
