So im looking for advice on planting an aquarium with discus in it im looking for something that i can grow over my drift wood to look very green and mossy looking. Also what type of grasses grow nice and tall that i can plant and eventually have them drape the top of tank and provide some shady spots. Also what type of c02 systems are the best and what processes are the best way to keep plants super healthy and vibrant. Any info would help thank you
