I already asked this question before but nobody replyed, so I'll make the question a bit more clear this time. I have a new 20 gallon tank with a Coralife 6700K 65 watt freshwater light. A Fluval 204 filter, and a Plant Gro Co2 System. I want plants that LOOK(they can also actually BE from the Amazon) like they are from the Amazon, and Amazonian water perameters. What would anyone suggest?
