I have been considerably lurking on here and thought I should creep out of the moss and introduce myself! A few months ago I went for a walk in the forests nearby and discovered a beautiful patch of moss. Some of it looked dead, some was alive. I took it home and planted it in the first terrarium I was creating. Within hours the dead moss opened up and turned green! I was so amazed!!! Since then I find myself looking at moss everywhere...and more recently I have also become lichen obsessed. Is it an illness? Can be a bit embarrassing at times! Anyway, next thing I am on the internet ordering aquatic moss of all things - not sure what happened there but I got a bit carried away I think! So now I have to learn how to get the aquatic mosses to thrive. Next thing I am reading up on substrates, co2, water plants and even killifish, oh my lawd - bit panicked about it all, think I have overwhelmed myself somewhat. Lucky for me I found this site. It's a huge font of knowledge, thank you everyone who contributes. I am quite relieved to find that I am not the only one who goes to bed with a head full of crazy idea's.
