mizu-chan - thanks, yeah i'm digging the substrate too! I wanted to try black this time, it's about 50/50 eco-complete and black aquarium gravel
SeaSerpent - I've been flipping back and forth on the moss idea on the large rock, on the one hand I think it would look lovely, on the other hand, it'd cover up the lovely caves and crevices in the rock so i haven't decided, don't have the extra moss at the moment (it went to the DW that i definitely wanted moss covered :-P) so i'll think about it.
Tex Gal - The rocks are inert, the tall one lace rock, large one laying down is slate and the rest are also inert though i'm not sure what they are, no worries!
And thanks for the compliment, definitely still needs some more plants though!
