Tibees are tiger X bee shrimp. Neos are a different shrimp entirely. The first few generations may be plain, some may not. The crosses are almost infinite as tiger shrimp can include regular tiger, super tiger, black tiger, OEBT, BTBE, red tiger and more I probably can't think of and bee shrimp can be bumblebee, CRS, CBS, Goldens and any Taiwan Bees (though the trend now is to call Taiwan bee/tibee crosses Tai-tibees). And then the pattern and colors can vary depending on male/female (male OEBT X CRS female may have slightly different looking results than CRS male X OEBT female). This is why most people don't fool with them, you would have to have unlimited tanks almost to see what all you can get.
What you have are wild variation NEOs, that's what happens when you mix colors.
