oooo, those are some excellent bettas. My favorite patterns are probably... deep or steel blue with black heads, teal dragonscales with red or black fins, and koi patterns, and I like the short tails on plakats (and female bettas). Much to my former betta breeding friend's chagrin, I'm also genuinely a fan of blue with flashes of red on the fins. I don't think there are any betta patterns I dislike, to be honest.
