Well i came to this thread to request some LOW light, non-green plants, but of course got caught up in some of the more recent posts and just wanted to say that in MY experience, Hygrophila difformis (Wisteria) can and does grow well under my low-lighting conditions. It grows up with strong stems in both my .75 wpg 20g H tank, and my 5g 2.5wpg tank. It grows FAST too, and does not become "leggy." And my small Crypt wendtii red may as well NOT just be plastic, as it has gone from about 5 leaves to about 20 leaves and grown about 2+ inches in the 6 months i've had live plants in the tank (this is my .75wpg 20g tall tank). So it's like James and others have said many times, everyone's tank is different, what grows in one may not in another. And I think that's a good, important, thing to keep in mind.
That's just my $0.02.
And I think it's a great list to use as a starting point, but getting advice about your specific tanks parameters and what might have a better shot at working than something else is generally a good idea anyway, and something that I think anyone who cared enough about their tank to have found a forum such as this would probably do.
But anyway....back to my question....
I need some more color in my tank, it's very...GREEN....any suggestions for low light plants that would add some different color to the tank?
as always, thanks in advance!
