My female betta has been looking sick for about three weeks...She's been getting worse. I've asked for help at other fish boards, but they won't reply to me. I don't know what to do, I'm not as knowledgable about bettas as some people. It looks like she has dropsy, maybe, but her scales aren't sticking out at all. she's been eating fine, she behaves normally, but she's huge and she's losing color on her sides. Please help me!
