After reading about bichirs I heard that they sometimes enjoy "playing" in the bubbles of an aerator. Whether you believe the fish is simply investigating or really playing is up to you, but I do know that it cures a disease that has stricken many a fish. Boredom. How much fun would you think it would be to sit in a glass box day after day the same old neighborhood with nothing much to do? Now humans can go climb trees or play games with each other, but bichirs don't have the challenge of gravity and are not social animals. What would a bichir enjoy? Well that's what I'm asking you? Please give suggestions. I was thinking maybe some sort of ball with food stuffed in it. A ping pong ball maybe?
they seem rather smart
