I have 1 coral banded, 1 fire shrimp, and 2 cleaner shrimp. They all get along fine. Although I did put in 3 really small peppermint shrimp that I got from SWF and I'm pretty sure the CB ate them. Just be sure that the shrimp aren't too small if you're going to put them in with the CB. Don't mail order them from SWF because you don't know how small they'll be.
