Just a suggestion. Id move the Green Cacomba to where the amazon is (on the left) and move the anabis across into where the cacomba was as well as the amazon where the anubias was. I suggest this because where you have the cacomba, its in front of the val so you have 2 background plants in front of each other. IMO it look a little silly. You want your anubias and amazon as your centrepieces. Just a suggestion.
