Riccia growing up terrarium wall?!

[LiveMermaid07]

Hi,

I was sure I'd read that riccia is soley aquatic, but in the terrarium that I've had set up the longest (since last May or Oct, I can't remember lol), it has started climbing the front wall. It's nearly an inch above the waterline already!
So what's with that?

Obviously a new definition is needed.

That's pretty crazy!

The drip wall on the right is covered in riccia. There's constant moisture but its not fully submerged.

To me ever since I first got Riccia it seems like its one of those plants that are hard to kill. Side not great looking setup. The constant moisture of the drip wall helps it. I know one of my tanks its sticking out of the water and has just a little bit in the water and it has no problems.
