Can betta dance?

[kotenok]

Hi, here is an interesting question can betta dance? I just saw my betta doing strange movements... here is a link to the video (if you want to see it)

too bad i started recording it too late. Does anyone know if it is an actual dancing or maybe it is something wrong with my fish?

it just swims up and down while shaking his head...and he did it like 10 times in the row... it was funny actually
