Buy a Hibiscus or other "Cham safe" plant
They're sturdier than hanging plants are and they give your cham plenty of cover.
Just be sure to thoroughly wash the entire plant first, since many stores/nurseries use insecticides or fertilizers on their plants. (The employees may have no idea about this, so wash the plant instead of asking them.)
Bring a tape measure to the store, so you get one that's not too tall or too small.
