I know of no reports of M. ramirezi being collected in the Negro, but only in the Orinoco Basin. Someone correct me if I'm wrong. C. melini is known to occur in both systems.
Thank you for clarify!
Did you know if the plant list are the same in both places?

Salvinia minima is known from Brasil, Colombia and Venezuela. But that alone doesn't say whether it occurs in both habitats. This is also the problem with Echinodorus grisebachii.
The only one I can tell for sure to be found in both habitats from footage from both river systems is Nymphaea sp..

Not fitting are:
Hemianthus micranthemoides does not occur naturally in South America. Limnophila aromatica is not from the Americas at all. Vallisneria americana are seemingly known from Venezuela and Colombia, but not from Brazil.
Cabomba caroliniana occurs originally far south of both habitats in southern Brasil, Argentina, Paraguay and far north in the US. It could stand in for species in the other habitats.

Looking at both habitats, I would say the habitat of Microgeophagus ramirezi has far more aquatic plant life, as it's a species from soft, but not that acidic habitats. They are a clearwater species, not a blackwater fish. The blackwater parts of the Rio Negro basin are mostly devoid of plants. Some pools that hold water in the dry season and sluggish side-arms have monospecies habitats with almost only Nymphaea and some floating plants or Cabomba dominated patches.

What you could do to focus on one habitat: Keep the Salvinia, Nymphaea and Cabomba and replace the cichlids with a species from the Rio Negro. Or replace the Corydoras with a species from the Orinoco basin , make the tank more open and well lit and sort out the non-south-american plants.

Going the Rio Negro route is less work in my opinion.

Thank you for your suggestions and answer my question!
For now, I just will refer my blackwater aquarium, and later do the changes to one of them (Orinoco or Negro)

Hallo,
I am Hanzle from Holland and keep apistoos for 40 years. Had my own aquarium shop from 1984 till 1988. Always s great fan from apistoos and hyphessobrycon which is s great combination in a Community Aquarium. Perhaps.....in the near future I start breeding apistoos again. Have a 400 liters Community aquarium for hyphessobrycon wadai and apistogramma biteaniata.
I want to get a 55 gallon slightly planted tank with many caves and I am thinking of getting 2 electric blue acaras, 3 blue rams, a apistogramma, 3 angelfish, and some corrydoras. Will that work if I keep the temperature at about and 80 or less?
I have kept fish for quite a long time but never cichlids. I want to find out more about them.
Hi

Hi Fred, do you have any apistos for sale? I'm looking for Apistogramma trifasciata. I'm about an hour and a half from Mtl.
