This one's actually red. Her name's Orlando, and the camera caught the lighting wrong, so she looks red. She now lives with another user on this site.
However, I did have a very pink dragon betta. I'll PM you her album. (It won't let me post urls.)
Her name was Leliia. Sadly she died last April of wound complications.
The first picture you'll see is the best picture I got of her true colors. You can tell that it took a lot of pictures to get that one. :'D
She's still the only betta I've ever seen with the true pink color.
