If you are cooking hamburger for dinner, then take a tiny speck raw and give it to the beta. They love it. I had a beta for 4 years and he was very friendly. They like the feel of a human finger and will curl around it if you put your finger in the bowl just barely. I fed mine some type of shrimp that I got at a tropical place, you kept it in the freezer.
