Hard to tell how good the light is from just a picture..Ill assume you bought it with a 3 gallon kit? The ligh probably isn't very powerful. Some lowlight plants that would do fine are Hornwart, Moneywart, Java fern, Java moss, dwarf hair grass although it wont spread, small clumps would do alright. Tip: Most plants that say low light will do fine in that lighting, I gave you a few good ones im used too.
