The one with the white is a Red Rili.
If you are intersted in doing some breeding projects.....
You coud try Red Rili, separate all the Red Rili coloration to one tank. Keep separating all the shrimp.
"Culling" doesn't mean you have to kill off the ones that do not meet the standard.
You can use lesser colored shrimp for a planted bowl, or in a tank with fish who could possibly nip them but really shouldn't be a threat. And they clean wonderfully.
Take all the darkest reds especially selecting the darkest red males. Keep the two groups separate. Move the less colored reds as you see them grow up the the regular red Cherry shrimp tank, and the same with the Rili babies. Just scoop to the best color appropriate tank and keep the net near in case you see a shrimp in the wrong tank.
Just letting them all stay mixed up is a mistake if you love the really red ones alot. And you should as they are more valuable. People love the Rili shrimp too. And they can morph blue /red rili, and Blue Velvet (BV).
The person I got my really red shrimp from had bred the my BV's from their ancestors!
As mentioned the russety red brownish can make chocolate and black and deep black blue!!!
It was quite exciting to see what would pop up next with mine.
Keeping the different colors separated and breeding is the line breeding. Culling is of highest importance though.
