These girls are my moms, but we don't know what kind of tails they are.
The light female is named Jaws, and it fits her perfectly, which is why she is in the glass. It is temporary, my mom bought her from aquariumfish.net, and she is the meanest little girl I have ever seen. Anyway, what kind of tail is she?
The darker one was one my mom bought from walmart, she saw her and just felt terrible for her, and saved her from the numbnuts who don't know how to take care of bettas, even though it is a part of their job. Its a miracle she made it, she had so much old food in her cup, the water was so foggy you almost couldn't see her, she "respectfully" brought it to the managers attention and schooled him a bit on how his employees should take care of them. Anyway, we also can't figure out her tail, what kind is hers?
