I mean to me its seems like those would be perfect to use. not many differations in colors. like how some bettas could have a red splash, and to get rid of it u breed with yellow. but then geesh doesn't that effect the other colors? just always seems to be something to always fix not just a perfect end result.
Once marble is in its hard to get out. Especially if you want to work with solid colours.
Cull hard and select breeders carefully is the best way to get good coloured fish.
Select fish with less red wash,or use red loss gene and work out the clear wash. Easiest way is to start with 2 good fish
