Depends on the shrimp and the fish. I've seen shrimp that readily eat fish, and fish that readily eat shrimp, and lots that co-exist just fine. If you mean cherries (or other shrimp that also fit in that size range and breeding ability), then they can be kept with many types of fish as long as you provide amble cover for them to hide in. Babies are tiny (around 1-2mm), so pretty much anything that eats can eat them if they have a chance. The shrimp are also very vulnerable when molting, so even a guppy can pick an adult cherry to death right after a shed. The shrimp are pretty fast though, so again, as long as they have a place to escape notice, it's not a problem. They will definitely be eaten, but should reproduce fast enough to maintain the colony. You can buy individual shrimp, but if you really want to have them long-term, you should start with at least 10 so they can start breeding-- it's a lot easier to maintain a colony than to try to keep individual shrimp alive. I have shrimp in pretty much every tank here that has small fish in it (the larger fish and packed tanks clear them out), but a shrimp only tank is the way to go if you want real numbers. A heavily planted 20 gallon tank with 200-300 cherries swimming around looks really cool.
