Willow Hygro Question (Hygrophila Angustifolia)

[Brian_Nano12g]

Just wanted to know your thoughts on Hygrophila Angustifolia? I've read online that some aquarists look at it as a weed that will take over your tank, while others enjoy it.

I picked up two stems of the immersed grown type from my LFS. They said it should do well in low-light non-co2 injected setups. Well I have a low light tank with gravel and root tabs as my substrate. Do you guys think it will do well enough and grow roots? My Anubias Nana, Swords, and Java Fern all seem to be doing well.

Here's what the Willow Hygro looks like in my tank.

Regardless this stuff is crap (excuse my French)... The clerk at the LFS said that it would take root short after putting the "cuttings" in the substrate. This stuff failed to do so and instead started to die and form a white string like fungus (like thin strands resembling cobwebs).
