To keep and breed ghost shrimp, you will need lots of hiding spaces for the babies, and female and male ghost shrimp. The way to tell is to look for a red dot on one of their legs. The other gender doesn't have this dot but I think the male doesn't, and the female does. Other than that, their is no really important equipment to have except for a filter that doesn't shred them. Feed them sinkable wafers as food, or just fish food.
