I'm new here but... This is my new blue betta! I finally got another one. RIP Claude. I've had him for about a week and I still don't know what to name him! He's really aggressive but he's very social and friendly. He's solid blue. And I still don't know what he is. I think he's a halfmoon but I'm not quite sure. That's what they told me. What do you guys think?
His fin on the top doesn't look like that all the time. He's not flared and I took this picture at a weird angle.
