I believe Wisteria needs medium light?
If you go here:
you will be able to find quite a number of low light plants. Heather is a great gal that answers questions, ships in a timely manner, packs well and has VERY nice plants (just got two more from her today). :)
I have moss balls in most of my tanks - low light is fine, but they don't seem to really grow. Kinda cool looking though, IMO.
As far as dust & such in tanks - I forgot to mention that I also have a parakeet & 3 parrots that all get out of cage time (all have clipped wings) so I am pretty darn confident that besides just regular household dust in the tanks there is most likely also a good amount of feather dust. :)
