Betta fish. There are certain elements of the natural world that are total headscratchers to me.
Butterflies, for example. Their beauty is unparalleled yet why are these insects given this level of craftsmanship, while others like the fly are left gray and unappealing?
Bettas fall into the same category. The Flamenco dancers of the sea. Their fins are hypnotic. I decided a series of these gorgeous creatures might be necessary.
