I called my betta Kaze because he reminds me of a gentle breeze. The way he flows around his tank and is always on the move just made me think of the wind... which ironically is something I don't get to feel much (at home a lot).
I thought I'd call him "Kaze" (Japanese for wind) instead of "Wind" or "Windy" because I simply preferred it hah. Japanese is a language that I've always liked... though foreign languages intrigue me no end anyway.
I understand where you're coming from though, it can be a bit confusing.
