Fissidens fontanus Moss

Fissidens fontanus is my favorite moss in the hobby right now. With fronds that curl down, and layer upon themselves, it’s a very unique looking moss. The effect is completely different from any of the other mosses in the hobby, as Java Moss, Taiwan Moss, Willow Moss, Christmas Moss, etc all give a similar look, despite minor differences. Fortunately, just like those others, however, Fissidens fontanus is just as easy to grow, and readily attaches to the hardscape.

Similar to any moss, detritus tends to accumulate within, and can ultimately lead to some algae being intertwined with the moss. I use Amano Shrimp to graze on these bits and keep my moss clean. F. fontanus is a North American native moss, with distribution throughout much of North America. As such, it can tolerate a range of temperatures.

Attaching it to wood/rocks is easy. Simply take a few fronds, and tie them down with cotton thread. By the time the cotton disintegrates, the moss should have attached itself. Now readily available in the hobby via hobbyists and online plant resellers, Fissidens fontanus is a moss that everyone should try.
