I have a small school of cardinals in my shrimp tank and the shrimp are always visible! I have lots of cover, driftwood, moss, etc for them to hide in, though, if they need it, but the shrimp often hang out right in the open, even swimming around. I have seen a cardinal nip at shrimp before, but only when the shrimp are swimming in the open during feeding time.
Tank is a 10hex, and fish and shrimp seem to inhabit all levels of the tank at any given time, but there are lots of things for the shrimp to climb on throughout the height of the tank.
