I have been wondering on goals with betta breedings in the future. The first picture shows a pin or sword in the middle of the caudal of the betta fish. Some resemblance to the future of this traits are w/ HMPK's, some show a little point at the middle of their caudals. The second picture is something that maybe needs rocket science to make it true! Imagine a betta, with two caudal lobes not stacking, but placed side to side like this Jikin Goldfish from Japan. This would become a new style of showing bettas, top view.
Any other ideas for new betta plans feel free to post below. ;)
