Mine love it! I was watching for about an hour tonight and my blue cobalts actually took turns going in the bubbles down to the bottom and letting the bubbles carry them up! It was so funny. The others waiting there turn! Haha, sometimes 2 at a time would go, they would fight to get to the bottom and let the bubbles shoot them to the top!
Normal? Do fish play? This is awesome!!
