Here's a couple of images. Not as good as the above, but to show the moss slowly taking over. crimbo-3 by saintly's pics, on Flickr crimbo-2 by saintly's pics, on Flickr crimbo-1 by saintly's pics, on Flickr This layout has been a great exercise in learning how to grow moss. I know for many, moss is easy. There are a few who are masterful with the stuff, but for me in the past, it was a nightmare. It would grow brown and not look too great at all. Over the last few layouts I've managed to get some really healthy looking moss, and this tank has to be my healthiest moss to date.
