Constant pruning is very important to keep Fittonia houseplants looking good. Cut back existing stems to about 8" above the soil line. This encourages the plant to branch out all along the stems. Once new growth appears, continue to pinch back growing tips once stems get about 6'-8" in length. Move your Fittonia to a bright, humid, location. Keep the soil moist but not soggy. Fertilize every two weeks with a basic houseplant food at 1/2 the recommended strength once new growth appears, never fertilize if the plant isn't growing.
