I know most sites and breeders suggest cooler temperatures for Neocaridina, but mine thrive in all my tanks that range in temp. from 79-84. Cherry shrimp don't lay eggs, they carry them until the young hatch so it's possible your guppies are eating the young, but you should still see some surviving if you have enough cover. Even though all my tanks are Pleco breeding setups, all have dither fish (guppies, tetras, rasboras) and it doesn't seem to slow mine down at all.
Although Cherry's are some of the easiest to keep, shrimp are sensitive to swings in water quality, especially nitrites. The smaller the tank, the bigger the swings.
