I beleive they all get along with the acception for
coral banded shrimp. I have/had pepermints,saron,sexy, cleaner and camel backs all together at the same time and all was fine shrimp wise but I have heard that there can be a level of "shrimp density" that could cause a fight. it is generally undefined what that level could be. If in a large tank then it is most likely not an issue. I have seen my saron shrimp eat my arrow crab (salinity shocked the crab during a water change and the saron grabbed him up before consious again, the arrow had made a meal of a shrimp in the past) so I guess they can be opportunistic. My cleaner met his own demise, being too out going. he kept trying to rush a
sally light foot crab off an algae waffer and the crab abliged him, dropped the waffer and grabbed a shrimp dinner instead. the other types of shrimp are displaying safe behavior.
