Japanese Dwarf Rush
So I received an order of plants from liveaquaria today. In my shipment was what I believe to be a Japanese Dwarf Rush.
I wasn't sure what it was, but I threw it in the tank anyway. After a bit of research, I've come to find that it can't be grown completely submerged for extended periods of time.
My question is, how long can I leave it in the tank before it starts to deteriorate? Also, would putting it in a glass vase with some capped miracle grow and a few inches of water keep it alive?
