What fish should I add to my community tank?

[Big Sexy]

Currently I have a 30 gallon, planted, freshwater fish tank.
It contains:
1 Dojo Loach
1 Pleco
1 Albino Cory Catfish
2 Orange-Finned Fish (??)
3 Zebra Danios
3 Neon Tetras
5 Large Black Tetras

What else should I add?

I would add more cory catfish they look nicer in a bigger school and they act more calm.
Good Luck!
