This is Thumbelina (Thumb), she was sold to me as a “half-moon” female betta. The first picture is when we first got her she was all pale (thumb colored) but had heterochromia I found that interesting. Now the video was today about 3 weeks later and she is getting very shiny and has a tiny red patch on her lower fin. So moral of the story I’m not to sure what she is, I’ve been reading the eyes are common in Koi betta and marbled betta so maybe one of those? I’d appreciate any help anyone has!
