Thanks all!
Mgamer20o0 - I'm gonna stick with this Ludwigia a while and see how I like it. Oh, and thanks for the tip on the blog. I just started one up! Oh boy, another aquarium-related online thingy to blow my time on... my wife will be so happy!
Squakbert - Nope, not a Tokay. It's a Henkel's leaftail gecko Uroplatus henkeli.
Phanmc - It is pretty weird looking, and I too had my doubts about it really being L. senegalensis, but I'm pretty sure it is the real deal now. See, what I didn't plant in the nano, I left floating in my bigger tank right under 110 watts CF with injected CO2... Sure enough, only a day later, and it has the distinctive leaf venation and green-to-red color gradient characteristic of L. senegalensis.
I just tediously planted a bunch of HC, stem, by stem, by stem, throughout the foreground with the other plants. Hopefully, like I said earlier, it doesn't just overtake everything and choke it all out (fingers crossed!). I'd love for the HC to just start filling in, and for the Crypts and Downoi to respond by growing a bit more vertical... and then they all lived happily ever after!
Anyway, I'll post some more pics when I get a chance - maybe over the weekend. keep an eye here and on my blog for updates.
