Might want to hold off buying more plants to let your plants will grow a bit more.
Then you can decide whether to add more plants as sometimes that works out well as having too many different plants can make it look kind of jumbled and more like a jungle rather than a planned natural layout.
But if you insist on buying more plants (very hard not to buy more plants!! I know!) you might want taller plant for mid to background area, I would recommend either a onion plant ‘Crinum calaistratum’ (one of my favourite plants) as it grows real nice long leaves that sorta waves in the flow, good for taller tanks. Easy to care for plant.
Or perhaps some Cryptocoryne Balansae, has wider shorter leaves, really lovely plant. And like most crypts, real easy to care for and appreciates root tabs.
The Tropica website pics does not do these plants any justice imho.
Btw I never had success with riccia fluitans, just died on me for whatever reasons, hope you have more success.
