I have ghost shrimp with both males and my sorority, and they are doing great and getting big. I make sure a bit of food sinks when feeding so they can scavenge it, so far they're all doing really well. I drop in shrimp pellets now and then as an extra food source, but my females will tear into it if they spot it so I don't know how much the shrimp actually get.
Nerite snails and assassin snails are fine as long as the male will tolerate them. He might not like sharing his space.
