Thanks for the suggestions Ed. Was thinking something along those lines.
Plant list so far...
Java fern - Trident (thanks Zeus)
H. pinnatifida
Buces
Mini Christmas moss
Crypts - C. wendtii green, kompakt, and maybe C. beckettii.
Rotalas
R. inundatus
Dwarf hairgrass or M. hirsuta
As for fish, small Hyphessobrycons and maybe a pair of Rams.
I've also got some lovely fern Marcel sent me along with an Aponogeton sp. which has just started to sprout leaves. Not sure if these are going in this scape or the 45-P, which I'll be scaping next.
