Stocking/Aquascaping help

This is my 29 gallon freshwater tank. I currently have one pearl gourami, 8 golden white clouds, and 3 kuhli loaches in the tank. What would be some cool tank mates to have in here? Also, how can I better decorate the tank/make it feel more homey (what are the easiest plants to maintain im nervous to get into that realm). Please let me know :)
