A few of my cherry shrimp have had this for 1+ months. I don't think it's spreading and am not sure if they came this way. Is it an infection? They've been in pH 7, KH 3, GH 5, nitrates around 20, sometimes higher. Just started changing parameters for Caridina a few days ago (no change in this coloration).
