Hey everyone! I recently discovered I need a hobby whilst sitting bored watching TV and have been amazed by the beautiful tanks people create. I'd love to be a part of it and create my own little world, however I don't know much about the technical side of Aquascaping, but that's why I'm here; I would greatly appreciate it if anyone could give me some information or just a few tips when starting a new tank. The tank I have is 40L so it isn't the biggest, but I feel it will be just a nice size. Also, I live right next to a dene with a little stream running through it. It's populated by little grey fish and covered in moss and other goodness. Would I be able to use moss/plants/fish from the stream in my tank?
