Who are you referring to? Id like to see purple neos! And also yellow with red?! I kept a tank of cherries, goldback, and orange Sakura for a while and just sold the whole lot to someone on a different forum. They threw mostly reds and oranges as well as some interesting green neos for a few generations, although they didn't stabilize and just ended up breeding out yellows.
You'll notice there are a couple brown shrimp in there. Surprised I had only a few as I added in ransoms when I had them (pearls, velvets, red rilis, Orange rilis, etc)
