Is co2 essential in a planted tank?

So I have a 10 gallon tank currently holding anubias nana, dwarf hair grass, and anarchis. I use Flourish, API Leaf-Zone, Flourish Root Tabs, and I am currently using a Marineland single bright led lighting system. I don't know if i can run co2 ever in this tank. So i'm just wondering if I absolutely need it in my tank. Also the 10 houses 1 German Blue Ram, 6 Neon Tetras, and a Otto. Please tell me your opinions.
