How often do you guys change you layouts? Basically I've had mine going since December. I am pretty happy with it I must say but I would love to have my tank slightly different. Mainly just with moss and crypts, a very simple layout which would be more about the shapes of the moss covered wood than anything else. What do you guys think? Should I carry on or try and create something new? I like the idea of trying to maintain it but I'm going to be selling my house soon and I don't really want to do another tank as well as this. Any input would be great.
