I've seen those types of bettas before. Its sad that they are bred to look like that. I do think all bettas are cute, but these are really sad looking.
That second male is gorgeous... too bad about the pectorals because they completely throw off the entire fish's symmetry and just make for a bad look. If he didn't have those he would be a stunner.
They're cute, but poorly bred. It's a shame that they can't move very well because of the way they were bred and that the last betta has a tumor on it's mouth.
