I voted "Other" because the Best color for a Betta is ALWAYS the color I am LOOKING for at the moment. This can change daily. Today that color is the deepest, fieriest most beautiful red you have ever seen with no hint of any other color in it. I want another Damon, in other words. I doubt that I will find one.
BUT let me say that if I should ever find a true grass green betta, I would be happier than a clam. I have tried to find a true green betta and they are rare. They usually end up being teal or turquoise or some oddball color not grass green. OR they change color on you after you have fed them for a few days like Alexander did. He arrived green and became blue as blue can be.
Oh well....my
