the best part is that your betta really looks to be dancing with the beat! I LOVE it!!!
My husband was a goof last time we went to the pet store (when he fell in love with the betta I ended up getting him as a birthday present)
He said "come here come here!" and dragged me over to the coy tank. There were maybe 5 or 6 coy in the tank. My hubby was following one particular coy with his head (not just looking, but moving his whole body to keep his head level to the coy) and the coy kept trying to swim in some evasive maneuvers to get away but couldn't. He did that for like 5 minutes, and I just wiiiiiish I had a camera. My husband can be such a goof, but isn't too keen on animals, so that just made it all that much more cute and funny
