How is the fissidens doing? I want to use it in my Dutch scape, but with all the controversy a couple years back as to whether it was truely aquatic, I'm not certain. A while back I followed a huge thread at APC with experiments and everything, and based on the evidence from that thread, I'm on the fence with it. It's so popular now, though, but most of these scapes are shorterm, so technically a non-aquatic can thrive for a limited time under those circumstances until it begins to decline.
Your other mosses look great.
Love the arrangement of the wood as well.
