@opae ula related is right, I also want to add that my baby shrimp tank when fed all flurry around and turn pale, maybe it's an age thing where they feel unsure or startled too easily and all go pale quick as opposed to the adults that tend to take a bit more unrest before they lose their colour.
My 3rd baby tank started to breed. I saw 2 berried shrimps today.
1st berried shrimp
2nd berried shrimp with about 30 eggs.
Added in 7 minutes 54 seconds:
I took quite awhile to stable the tank and the shrimp color is more visible now.
