We just found out we have a betta with the marble gene.
He was a solid dark blue crowntail when we got him in July. He's the blue crowntail in my profile pic. He started with just patches of white on his dorsal fin and cheek in November... and everyone told me it was a bacterial infection. I tried everything to help him get better, but nothing worked.
It spread and spread, until his entire body was white/cellophane color with some orangish red on his back, head, and a little on his fins. I never knew what the marble gene was, and everyone in forums and pet stores told me he was sick... so I took it to mean he was about to drop dead and we were sad.
Turns out... yeah... he just has the marble gene! He's one of those fish that changes drastically! but we are so happy he is not actually sick :D
The marble gene truly is interesting XD
