I would switch the wisteria and scarlet temple. If you don't you'll be trimming the wisteria all day long, everyday. Wisteria grows so much faster and bushier than scarlet temple. Also a bright red bush at the front of the tank will look nice.
Buy extra stargrass, pretty much the entire bunch we ordered melted and it has taken about 3 months for a few tiny stems that didn't melt to take root and start growing normally. I have less than a 2x2 area with stargrass in it after 3 months.
It's personal favorites but Ludwiga is one of my favorite plants. I'm looking forward to getting some red ludwiga, I don't have any yet.
I think it will look nice. :)
