What are the chances of doing a Central/ South American blackwater biotope? The idea is to have an ecosystem of sorts with oscar, hujeta jar, jaguar cichlid and kelberi bass as the apex predators with many smaller schooling fish ( neon tetras and pygmy corydora for clean up crew along with apple snails and shrimp).
What is the chance that it would be succesful in a 300 gallon tank with botanicals and fast growing plants?

thank you for any feedback

The rub with doing a south/central biotope, is that the waters in Central America are so different than the waters. in South America.
Waters in Central America are generally hard, with high pH (8 or above), and waters is South America are generally soft with low pH (7 and below), so most of the fish species from geographically opposite biotopes don't really belong together
The biotopes may look similar but are quite different chemically .

Where I live in Panama, near the Mamoni river the pH averages 8.2, it is quite hard, and the fish species have evolved a tolerance for hard water bacteria.

Just a 45 min flight away, in the Atabpo river in Colombia the pH averages 5, has little to no hardness and fish species have developed resistance to the bacteria that live in those conditiones.

If it were me, I'd determine the parameters of my particular tap tap water, and choose the biotope, and its fish species accordingly.

Welcome to MFK! For a Central/SA blackwater biotope with those predators, I recommend keeping those predators and maybe a large catfish or two, no pygmy corys or neon tetras, they will be an expensive snack. You could also do a giant school of pygmy corys and neon tetras in their own setup rather than mixing them with large predators. That would be awesome to see.

Good luck! Can't wait to see what you come up with! :D

Thanks for reply
What catfish do you recommend? Maybe lima shovelnose? I like perruno but i am scared that a fully grown perruno will try to eat pimelodus blochii which would also be in the 300g

Hmm....maybe an Irwin's Soldier Cat? Tiger Shovelnose? I'm unfamiliar with larger catfish; others can provide better help in that department than myself. Check out PlanetCatfish. They have a lot of great info on tons of species of catfish. You'll be able to find what you're looking for there.

I love Striped Raphael Catfish (the smaller cousin of the Irwin's Soldier Cat). Striped Raphs are total tanks; they can put up with anything. But unless you get a large/huge adult, it may not be suitable with some of your options.
