I like my Vallisneria and amazon sword because they do give the jungle vibe. I also like pogostemon octopus because they grow fast and easy and once they are big enough it will certainly give the jungle vibe. Just keep trimming it to make it grow denser and denser.
My betta tank is the only tank in my house that grows plants very fast even though i didn't so special ferts or light for that tank.
Maybe you could look those plants up and maybe you'd like them
I don't have the octopus plants in his tank though, i have it in my other tank.
