I decided to rescape my 60 P and go with a central mound type layout with stone/driftwood and anubias petite at the center of the wood. I plan to have a green "bush" (let's see if I can trim it that way :doubt

of Rotala sp. "green" behind the wood arrangement. I ordered some Rotala macandra "narrow leaf" to add a red accent to this bush.
My question is what is the best way to plant the red stems?
1) Plant all the reds as a single grouping right in the middle of the bush?
2) Intersperse the red stems along with the green but more or less in the central area of the bush?
3) Have a small grouping of reds arranged as one or two rows all at the back of the bush?
4) Some other arrangement?
Thanks for your suggestions!
