Plant identification

What is this plant? The friend who gave it to me doesn't know what it is either. It just thrived in his tank.

Susswassertang. It is a fabulous moss.

Susswassertang.  It’s essentially an immature, aquatic form of a terrestrial fern.  It forms lovely mounds of bright green like this when it likes the conditions.  It can be a bit picky and randomly disappear when you first get it.  Remnants of it often adapt and you’ll find regrowth when and where you least expect it.  It is also a bit fragile and pieces that break off can spread elsewhere in the tank whether you want them to or not.  It is pretty easy to control by just plucking it off from where it’s attached and moving or discarding (or selling) it.  You can also scissor it back if you want it more controlled, but you’ll want to corral all the stray bits unless you don’t mind if it takes over random spots in your tank.  Terrific for tiny fry and shrimplets to hide, impossible to catch fry and shrimp out of it.
