I tried breeding a double tail male betta into a halfmoon candy koi female betta to produce huge dorsal candy kois.
Here is the 1st part of the project.
The 1st scenes are the breeding
Then the growing of the tiny betta fries into a little over 7 weeks old.

The 2nd part of this, which focuses on a single betta from this spawn in his juvenile stage into a mesmerizing adult multicolored galaxy koi betta will be uploaded next.
