I would like to try adding a floating plant to my 55 gallon aquarium to see if I would like it. I mostly have a variety of different types of java ferns and anubias in there now. I have seen a floating plant in several your aquarium pictures posted here that I like, but don't know what it is. I'm hoping if I describe it, someone can identify it for me. It is fairly light green and the roots are short (around 3") and feathery instead of long and stringy like several kinds I have been looking at. Thank you for any help you can provide.
