Hi,

I think it is more personal choice. I only have experience with Java moss, but I understand that most grow similarly.

I think if it is attached well any type will do fine.

Please also note that if conditions are good, you will have plenty of moss and will soon be giving it away. Keep in mind when initially planting the wall as you won't need that much to start is all I'm saying.........

A little current across it will also help to keep it clean and algae free as it will attract debris. I give mine a shake every now and then or even remove large bunches, rinse, and replant/reattach.....

Good luck and please post a pic when done!
