Betta Fish: Taught my betta to chase a plastic ball pin like it’s prey.

Was trying to think of ways to entertain my boy perseus and I thought chasing something is probably a natural instinct, so I got a pin and immediately he loved it. He now knows that every time he catches it he will get a treat so he will turn around and wait for his treat once he has got it. My other betta pitbull isn't a huge fan of it, his fins drag him back and he's super smart so usually he notices it is just a pin and will ignore it. Its also good to use as a guide for my partly blind betta to use for finding his food.
