Go for the riccia man, it's awesome. The dwarf var. is so easy to work with. I found hairnets easier than nylon line too.
Cheers for the Chakra link too, most fascinating.
Update -
Added my first fish today. After some careful thought I went for five Microrasbora nana.
It's hard to get a sense of scale from this photo so I'll try get a full-tank shot tomorrow. Believe me they are small.
I really like their relatively plain look. For me this compliments the simplicity of my aquascape, rather than contrasts perhaps excessively like say a cardinal tetra would in this instance. I've always considered fish selection very important for the more "serious" aquascaper, and I think leaving the decision to near the end of the aquascape's maturity is a worthwhile experience.
