IYE, Neocaridina (in this case RCS) do seem to flick away when scared, or try to eat whatever I poked it with. Caridina (in this case Amano and Bee shrimp,) seem to walk away, then flick away if I pursue.
I also noticed that Caridina aren't very good at sharing food. They seem to pick it up and run away with it, while the Neocaridina seem to pick at it and share it with 10s of other brothers and sisters.
