If you mean cherry shrimp, that sucks. If you mean crystal red shrimp, then that sucks even more.
In any case, adding juvenile shrimp to a tank with decent-sized fish like bloodfin tetras is pretty much asking for it. The bolivian ram probably took out a lot of your shrimp too. Did you add the shrimp in with the lights on? That automatically puts them at a disadvantage because they're stressed from the acclimation to begin with, and the fish can see them clearly, leading to a prolonged shrimplet hunt. If a single attack is even mildly successful, the shrimplet will probably be stunned for a long time during which it will probably be killed.
In the future, if you want to introduce shrimp to a tank with fish already established in it, then only add adult shrimp.
