This looks really nice! The flat marimo balls are a great idea and look so much better than the balls. Great job!
Thanks! I agree. I think they look better than in the ball form. That nymphaea micrantha is what I got from you. I moved it and damaged it, but it's bouncing back. It did have all sorts of new leaves, but I really messed it up pulling it out of the substrate to move it.
Quick question about it. How big to the leaves get and how tall?
