Don't hold out for success. I do keep a few cherries in a 20H tank with a few pearl gouramis and a betta. They survive, and even reproduce, but I don't ever see more than 1 or 2 juveniles after any period. The adult shrimp seem to figure out how to avoid the fish, but the youngsters don't really survive long enough to find out.
Give it a try, you never know what may work. Be prepared to lose your shrimp investment though.
