Very nice tank. I'm guessing you want the chain sword to fill in and leave the middle path of white sand free of plants?
Your sunset hygro makes me want to get some for myself more than ever. After wild success with rotala rotifundiola, I have a newfound love for pink plants.
Are you sure that's wisteria in the back right? The color looks off -- very very pale compared to the lime green it normally is. Also, the leaves look more feathery than they usually are. Maybe originally grown under super high light?
