I got both as Fissidens Fontanus. After 1 month turns out they grew differently in the same environment. Derived from this thread http://scapeclub.org/forum/showthrea...this-fissidens
Here's a picture of them. 2 on the left is Fissidens Fontanus, 2 on the right is unknown?
Help me ID the fissidens on the right please, I would like to buy more of these but I need a specific scientific name.
