Yes, the anarchis makes it look much better, i tried to get some cryptocorynes , but they ran out

Yeah, the bamboo does grow but not as fast as you think, we got it 2 years ago, it's grown like a few inches. It is currently 2 1/2 feet tall. I really like it how new sprouts or shoots just grow right out of the bottom. The shoots that are under water was not there before, it used to just be this stick with a few leaves, but the top has grown many sprouts and the bottom sprouts that are submerged, has grown by itself. And if it gets too tall, you can cut one in half and it will grow into 2 plants, the cut will grow new roots.
This one in the picture was cut from the main plant.

I'm glad that i'm not the only person that thinks that bamboo looks great
