I actually have four cherry shrimp in my tank with neon tetras, harlequin rasboras, cories, and bolivian rams. None of my fish care about the large cherry shrimp..but the babies. Forget it, those poor little babes are snacks in no time. The tetras are always the first to get em.
I would look into bamboo shrimp if ya want one. They're a bit larger. I've been trying to get my hands on one myself. I've also kept amano shrimp which were awesome. Bigger than cherry shrimp but lacking the bright colors, although they did turn a pretty clearish blue.
