I'm starting a new 20G (20x10x24tall) with an 18" 15 watt bulb in the hood. I want it to eventually be heavily planted with driftwood and moss and the works. I'm looking for suggestions on what plants would do well and look good in this kind of setup. I don't know much about C02, so for now I'd like to stick with plants that don't need it. I also want something that will get really tall so that I can make use of the full 24" depth. I really like the looks of hairgrass and moss...so If anyone has opinions or suggestions for those, that'd be great. Also, the tank has a mirrored back...should I try to cover that up or will it help make the tank larger? I'm open to whatever suggestions or opinions you guys have
