You are better off starting a 10 gallon shrimp tank with the correct water parameters (to include GH, KH and TDS test kits) and get a colony established. If the colony does well, you can transfer some of the older offspring into the fish tank.
If you want to do fish and shrimp it's recommended to start with a heavily planted shrimp tank, then add fish once you get a good colony. Cherry shrimp have short lives and fish can cause them stress, which means slower breeding. If you start out with a healthy breeding colony with plenty of coverage, you would have a better chance at it.
Except for ghosts, amanos and macro shrimp, keeping ornamental shrimp (cherry, crystal, tigers, etc) is a completely different ballgame to keeping fish.
