part of my a few days old Blue tigers has problems. Walking is incoordinated, limbs are in unnaturally position and awry. Molting is problematic. The problems result in death.
That really does not look like a Tiger shrimp. But it actually looks like an Amano shrimp based on the body patterns (dots). Again, if I am wrong about this, please let me apologize ahead of time.
It is really Blue tiger . Interchange is impossible. Just now I don´t try to breed C. japonica. I keep every my species in separate tank. You often can not compare young and adult coloration. It differs notably. Young above is about 4 mm long.
