I know there are a lot of members here that have giant or king bettas. I got one of my own about a week ago. He's a teal and black plakat male named Spica. (Get it? Spica is the name of a blue giant star.
) Unfortunately, I don't have any good photos of him.
I'm especially interested in seeing halfmoon king bettas. The Petco that I got Spica from had a beautiful male halfmoon king today. He was bright blue with a white "butterfly" marking on his tail. He looked like a 4" long HMPK. I would have bought him, but he cost $30, and I can't stomach spending that much on a pet store fish.
They did have him in a 5 gallon tank to himself in a secluded part of the fish section, which I thought was nice.
Anyway, I'd love to see your giant bettas.
