Definitely haven't seen that color variation before.
Really curious to see if the colors on your fish get more intense once it settles into it's new home.
If bred this fish, you need to choose one with a more recessive gene. I don't think yellow is dominant at all.
- If you ever get around to spawning a neon fry out of your crowntail female, I would trade you for one or two of my phoenix orange juvies later this summer.
BTW, how many centimeters long is your neon betta?
