I know this thread is a little out dated, but I found something super fun! There's a product called "dial a treat". It's a little red circular container with bloodworms, mysis shrimp, and daphnia. The spoon that comes with it has a little prong on the other end and you can stick the food in the prong and let them chase it. I expermiented a little and it also works greatwith pellets. Yay fun things for our bettas!
In the edited words of a disney princess, may all of your fishy dreams come true. ^_^
