White cherry shrimp?

My RCS shrimp often are colorless when they first hatch. This way they can hide better from predators. I would wait and see if they develop their normal color in a few days. If water conditions are not optimal, shrimp may also loose their colors or fade to a lighter shade. But if your adults still look normal than that is unlikely. When I do water changes in my RCS tank, I have to use a magnifying glass to check for baby shrimp as all that can be seen are the eyes in the first few days. This is a little easier with CRS as they start out showing some red right away but with RCS it's not unusual to have the shrimplets starting out colorless. And I don't even want to think about how many I may have tossed down the drain not realizing that there were babies in the tank.
Did you change anything out in the tank lately? Like different décor or plants (more or less of them)? I found my shrimp show more color on darker substrate and in a darker tank than in a tank where it is very bright.
