I really want to start a bigger tank thaat i could actually put some nice plants in. Im relatively new to plants, but not to aquariums. I'm going to get a 40 gallon long aquarium (anyone have one? I've never heard of anyone having a 40 Long), the dimensions are 48" by 12" by 16". I really like the look of black sand and plants would stick out and look pretty cool. I'm not sure about the lighting. this is the fixture I was planning on getting:http://www.fosterandsmithaquatics.com/product/prod_display.cfm?pcatid=22134 but I'm just not sure what kind of plants these lights would support. I need design ideas also, all I know so far is I want a big piece of driftwood in the center. Thanks guys!
