Those are some gorgeous bettas Zenandra!!!!!
Wow, I am horrible at this, but...
..Well, judging from the betta tail type listing, double veil-tails... maybe marbled black and pink (or white, or whatever you want to call the coloring of your female) fry... with blue on the fins.
They would go great together, you should breed them sometime if you're up to it!
Alrighty..Peanut- Red dragon Delta (or superdelta, according to Zenandra) PK- (whose fins still have to heal after a fight with a betta at the breeder's)
And Hattie (sorry, only a video, she's coming on Tuesday)... It would be kinda hard to tell, but she's a Blue Dragon HM- the second one, or the one in the middle. Between 00:37 and 00:39 displays her colors really well.
