Neocardina heteropoda var. 'Blue Pearl'
This is confusing... do you mean neocaridina cf. palmata "blue pearl"?
I remember reading people said neo. cf. palmata aka "Blue Pearl" or "Snow Ball" (used to be classified neo. cf. zhangjiajiensis) bred with neo. heteropoda led to sterility and weak shrimp.
If that's the case, way to prove them wrong!
