What Plant Should I Get?

[ZephyrStarPlaties]

I've just discovered that two of the three plants I had in my 20 gallon aren't aquatic, so I planted them in the window box. But now I need some new plants. I need something that is 10 inches tall maximum, doesn't need added co2 or fertilizer, and doesn't need a lot of natural light. I'll also need pictures so that I can find it at the store.

Java fern - although you will need to attach it to something
