very nice, thanks for the FTS
(sorry sometimes I forget I used to have no idea what the meant either :-P) I love the colors, and I think it's awesome that you can get that gorgeous obsidian! A very cool look, very unique, i like the way you used it in the scape too, very nice.
On your plant clippings though, don't think no one will want your fast and easy to grow plants because you think they're not special. I'm sure they'd sell fast in the swap 'n' shop, especially if they're something you're going to toss anyway, if you only charge the cost to ship, they'll be gone in no time. A lot of people setting up their first tanks or are just getting a new tank started would probably snatch up packages of fast, easy growing plant clippings! Just a thought
Anyway, gorgeous tank!
