Just idea..... how about swapping the fissidens over with the HC and have a bigger HC carpet in the open space?. This way you dont have to source a much fissidens...HC is far easier to get hold of

Not sure i am undestanding you there Fishy. The Fissidens will only be a smallish patch as the darker green shows on the diagram. I know what you mean about it being hard to get hold of. I cannot find it on any sites like Aqua or TGM.
Not sure about adding moss to the rocks as i like the look of them, however i was looking at the tree in out garden that has ivy all around the bottom 1/4 of it and i thought hey i could do that using some of the moss
