which I forgot to mention in my last post. I cut off a piece of windelov fern rhizome that was growing off the driftwood chunk and headed down to substrate level. It only had three leaves, but removing that one piece makes the front pathway feel more open, and I can see into the heart of the windelov patch. I also snipped the rhizome in there, so the older bare parts will hopefully grow new foliage.
I moved the clipped rhizome piece and two young ferns that had grown out on the ends of mature leaves, into the window tank.
