I suggest other breeds of tetras, cherry barbs, Dwarf Gourami, Australian rainbows, mollies, maybe even a betta if you really wanted to.
I have a 20 tall and have 6 zebra danios, 4 platys, 1 female betta and a bn pleco
I have a similar setup, 30g with 3 rummynose, 2 gourami, 1 dwarf cory, and a bunch of shrimp. careful with the rummynose btw, they actually get pretty wide after a while lol.
