Süßwassertang is a freshwater seaweed that has recently been introduced by Oriental Nurseries in Singapore. It looks similar to Monoselenium tenerum (Pelia) but is not a liverwort - it is actually a variety of fern. It prefers cooler temperatures and does best with medium or greater light and CO2
injection, although neither are necessary.
I have not had the chance to check it out yet, but it does look interesting. I'd love to hear what you think of it Toirtis
