I like both natural, and colorful. atm I have bright rainbow rocks, and a neon cave, and a glowinthedark plant, but I also have real plants and rocks. No wood, but I don't have much space to work with..........YET......I would like more natural, but this is what I have atm. When I get a big tank it will be natural, and I hate those laser lighthouse things, and fake scuba divers.
