Plant recs for this 11 gallon long?

I just upgraded my boy Pomelo to this 11 gallon long from a 5.5. Moved over the plants and wood but it looks barren. Any recs on some plants to fill it out a bit more?

Low tech, only has a lone sad sagittaria, Anubias nana petite, and Java ferns right now and some floaters. I fert regularly with easy green root tabs and liquid ferts. Easy low tech compatible plants please!

Appreciate any suggestions!!
