As promised I'll go over this give you app. sizes so you know better what to expect from these plants...then I'll comment on the sketch
(Sizes are based of my exp meaning no ferts which they may grow bigger with ferts I donno lol)
1- Echinodorus Bleheri > Will gwo about 1ft in diameter and about 1.5ft tall
1- Echinodorus Rubin > Same as Bleheri just not as wide "spread"
1- Anubius Barteri var Coffeefolia > About 4-5" dia and about 7-9" tall
3-4 Zephyranthes Candida (Dwarf onion) > No pers exp here but I seen them grow in other tank around about 1.5ft tall
6- Villisneria Asiatica var. Biwaensis (Corkscrew val) > OK, I donno if these just "went wrong" in my own tank but mine grew some 2.5-3ft long (they were gigantic)
Limnophila Aromatica 'Hipporoides' > Like any good stem plant tall, but I clip mine at around 18" to maintain a high level there
Sagittaria Subulata (Dwarf) 7-8" tall and each spread out a lil I'd say 2-3" dia
On your sketch you also listed Crypt's they don't grow much taller then 6-7" but spread out nice & bushy around 10-11"
Now your sketch: I'd lay the DW across infront the Asiatica and then the E. Rubin & Onion infront of it
The Limnophila because of the size I'd move where the Crypts are now and the Crypts infront of it (otherwise you'd not see the Cypts having the taller plants blocking them.
Hope this helps
