Thanks for the replys guys! =) and the welcome haha.
I've been looking into which one to get, I finally discovered some locally so yeah, here in the near future I will. It makes that much of a difference huh? Which of the two would you recomend? Chances are I'll add a layer, as I'd be too lazy to change all the gravel haha.
Thx! and yeah, I'm impressed by the filter. Runs quite too. And hmm possible, I've never heard of that plant before, but the resemblance is amazing, maybe we could get some more opinions on this?? I have some growing in my 16g as well, its growth is slow in a low-light tank (1.2 wpg, further supports the fern idea i suppose haha) but steady. I'll take a close look when I get home at the growth in my 16, because the new growth is a broad leaf, then splits into thin leaves like that fern. the old LFS I used labeled as wisteria, but now I'm not so sure, I'll uncover the rhizome just in case.
