Biotopes are hard. Ivan Mikolji's youtube is probably the best channel I've seen to give guidance, if you are interested in future South American projects. You have to work with little info, as it isn't a popular type of tank.
I wish it were, but we don't all have the info or resources to do it. It's a still a glofish, fancy-bred fish hobby, fundamentally, and nature based set ups are not in fashion.
You're 17, and it will probably be some time til you're working and living in a stable space you can build things in. At your age, I read and read, and read some more, figuring I'd store up info for when I could use it, or not. There's never harm in learning. It's daydream fuel. I decided I wanted to get into a jungle and have a look when I was about 20. I did it for the first time at 48, for all of 6 hours. A real trip took til I was 65.
So whatever prep you make for a tank you don't have yet isn't wasted. Plan a hundred biotopes. Patience...
