A few angels for colour, school of neon Cory's or "laser Cory's", some fancy goldfish (lionhead's are entertaining), ONE Pleco due to their size, and possibly a female betta if it's docile enough... Also maybe a Pictus catfish and/or a sailfin molly, they look nice when fully grown. Good luck!
For my 30 gln community i have 6 bleeding heart tetras, candy stripe pleco, farlowella catfish, african butterfly fish and then a firemouth as the centerpiece
