I have a yellow or creamish color female that I bought from Petsmart for .99 cents a few months back. She was real small at the time I bought her, she is getting quite a bit bigger now. All the females at our Petsmart are .99 cents, the males range from 3.99 to 5.99. This is the only femal yellowish color betta that I've seen, I live in Illinois so they may not be that rare, don't know.
