I have this Peacock moss growing in one of my home made pods which sticks to the glass. The moss is really nice, green and no algae. It has been growing this way for some time and looks very natural. The pod that the moss originally started in is 6 inches by 3 inches about. All the moss was stuck inside and it grew out between the mesh. I use co2 in this tank with very little fertilizers...also have a ton of amanos which keep it clean. Comes with suction cups so you can stick it to the glass anywhere in your tank.
$45 for the entire thing. Pickup at Starbucks in Greenwich CT (06830). I'll leave it here for a few days and if nobody picks it up then I'll list it in the SnS section where I'll be able to ship but for now it's only for pickup.
Here is the cylinder before putting moss in it:
