indeed all our bettas are mutants of some type
mild rosetails are fine I quite like them.
but because extreme rosetails come with messy scales, unballanced finnage and extremely heavy branching, all which can be passed down to their children, most breeders get rid of them.
I'm not much of a DT fan either but my betta breeding goal requires their blood :evil:
I wonder if one day we will see "full moon" bettas with 360 spread... I dont think I'd like the look of them:sick:
