Very Interesting!
I'm sure some other shrimp (at least in Caridina) have eggs fertilized by multiple fathers as well.
I guess pairing only 1 male and female could pay off if you were looking for a very specific trait the male had.

Probably correct - I've observed multiple males trying to mount a single female among my CRS and Super Tiger tanks, perhaps each fertilizing/placing sperm as they do.
