I've merged these two threads since you basically are asking the same question.
First, are you sure the shrimp are still alive? Second, shrimp hide a lot by nature, and with lots of plants you can go a long time without seeing them. They are much more likely to show themselves if there are no fish or other potential pedators in the tank.
Cherry shrimp will eat a wide variety of foods. Since they can get a lot of algae, biofilm, and plant material in a normal planted tank, try giving them something with more protein to lure them out. Mine like any kind of sinking pellet, and really like frozen brine shrimp and blood worms.
Be careful not to over feed.
