Any LatAm fishkeepers?

I have been keeping silvertip tetras (small Brazilian tetra endemic to the São Francisco river) since 2023. These are the first fish I ever kept, and I didn't do enough research when I first got 6 of them for a 10 gallon tall. I have moved the 3 remaining ones (the other 3 died before the transfer; and they're 2 years old now) in December 2024 to a cycled 39 gallon, 3ft long aquarium (set up in November 2024 and cycled for a month before putting them in), and slowly added 15 more to increase the school size. The new, larger tank is a single-species setup just for that fish. I do have some questions regarding fishkeeping and the aquarium hobby in Latin America, however.

Are there any aquarists from Latin America that have been keeping tetras and other South American fish? What are your thoughts on keeping fish (most common aquarium fish are from South America) that are native to your area? Why do fish that come from South America (i.e. neon and lemon tetras, ram cichlids, angelfish, guppies) hold a special place in the aquarium hobby?
