ThanksThere are lots. Java fern, java moss, anubias, cryptocoryne, sword plants, Hygrophillia and the dried bulbs they sale at pet shops are all good, hardy plants. Java fern, java moss and anubias all need to be attached to driftwood or rocks, cotton thread is the best for loosely tying them in place. All of these are very adaptable to light levels and don't require extra CO2, all are good for plant beginners.
