@efmp1987 The brown stuff is just sphagnum moss. As far as I know it is dead, although I have seen people say that it started growing for them before...or are you thinking the four frogs in this picture are moss?
@miss moxie Thanks. They're beautiful...I wanna try and get some sort of live plants growing in there with them. And ya, I believe I saw some grow back to life in a video on SerpaDesign's Youtube channel.
