I have been struggling to achieve bright yellows in my betta spawns for a while. The previous generation created a variety of colors including red, blue, white, pink, copper, and a wild mix between. I paired a red female with copper male, both of which carried the yellow gene, and got this beauty! There are a few other yellow males from the spawn, but this guy is my favorite!
