I have a twin tailed (double tail) Betta and (IMO) they are gorgeous! i also have currently a veil tail and a couple others in the past along with a crown tail and the twin is by far my fav! their caudal fin never folds on itself or floats behind them. It's like its on perma-flair even when the Betta isn't flaring. so im saying go with the double tail!

Don't worry winged, he is for one of my best friends and I will be there to help them the whole way and to watch over Merlin. That's what we named the little cutie!
