Aquatic Eden has posted pictures of the top 10 tanks from Aqua Design Amano's 2008 International Aquatic Plants Layout Contest. Around the office, we generally refer to these beautiful aquariums as freshwater planted tanks.
ADA founder Takashi Amano, however, prefers calling them nature aquariums, or a "beautiful underwater world of aquatic plants and tropical fish."
If you're into the freshwater planted, er, I mean ... nature aquarium side of the hobby, give Aquatic Eden a read. There's a lot of great content on everything from diffusing CO2 to aquascaping on a budget.
