I haven't tried Tiger Barbs with shrimp yet (chicken, yup). Cherry Barbs are fine with Amanos and Neocardinas of a couple of species, but they are milder than Tiger Barbs.
I can't predict - it turns out I left Rednose in the tank turned over to the dwarf puffers - they are fine together. But DPs sometimes kill and eat Ghosts - go figure.
