Answer: Ruellia makoyana, or monkey plant, grows best in full sunshine. I think you're overwatering your plant. It does best in well draining potting soil and should be thoroughly moistened, then allowed to dry out between waterings. Instead of watering every other day, soak the soil then wait 7-10 days before watering again. Your plant should perk up in a few weeks.
Best wishes with your monkey plant!
