Adult shrimp should be okay, but babies will certainly be eaten by any sized nano fish. If you have a large enough shrimp population, with plenty of plant coverage, your shrimp population should continue to grow despite predation of baby shrimp by the fish.
My cherry shrimp population is still growing (though slowly) with more than 30 small fish in an 18 gallon tank.
