South American Biotope?

Would cory catfish, neon tetras, and skirt tetras live together in the wild?

My tank is stocked as follows:

2 honey Gouramis

5 buenos aires tetras

6 long finned skirt tetras

4 corydoras

I planned to trade my honeys, and buenos aires tetras to get some neons and plants.

My plants are as follows:

3 bamboo plants

1 red waterlily

5 anubias

2 water onion

I have 2 reptiles uv bulbs from a previous project. I was wondering if hydroponics bulbs would work?

What plants/ fish could I get to fit a specific South American biotope?

I have a 90 gallon tank and have recently come across biotopes. I have the understanding that cories, black finned tetras, and neons are South American. Any help or advice would be great! Thanks in advance!!
