Thank you AdamRt
The nigricinctus are very hardy. They are wild specimens which (as are all the tetras I posted pictures of above).
They do come from waters of low organics, so the tank they are in gets a 75% water change weekly.
They eat a wide-range of foods. I feed NLS Freshwater flake as staple and then rotate freeze-dried blackworms ( they love), frozen bloodworms with spirulina, frozen brine-shrimp, and occasionally, beefheart.
They are primarily insectivores in wild, so need a high protein diet.
Tank is at 78 degrees, good flow, lightly planted, driftwood.
Temperament: extremely docile ( would not do well but with aggressive fish), no fin nipping of other fish. Schoaler, not a tight schooler.
The females are coming to age, breeding form, and this summer I will attempt to breed them. Here is an article I found to breed them:

The Tocano tetra is solitary.
I had a group of 6 in a 10 gallon that decided to spring a leak at 11:00 at night and lost the other five. An expensive loss.
Its really hard to evaluate this breed as it is solitary and I am not getting the full benefit of natural behaviors. Right now he is hanging out with the nigrcinctus.
He eats heartily everything that feed the nigrcinctus. The temperature is a bit cool for him-- they like temperatures closer to 80-82 degrees. Been looking for more Tocano's so can put him back in a 10 gallon with his kind- have not yet located any others... I am actively looking.
This is the tank they are in:
The Orange Lemons, which are a group of 20, are in my 180 gallon South American tank with geohagus sveni and neambi, biotodoma cupido and wavirini, corydoras eques and brochis splendens, and the two African tetra varieties I pictured above.
This tank is at 78 degrees, is medium- low tech planted, driftwood, rock, sand.
This variety stays at mid level of tank and will often go to bottom of tank to feed. I have a heavily planted background of valisneria which the group inhabits on one side of the tank. In my tank, it doesn't school, but prefers to hang out as a group in the tall valisneria. During feeding it will leave this area and go throughout mid to lower levels. Its behavior was a surprise to me-- thought it would school like your more common Lemon tetra- but its behavior is quite different.
They eat a varied diet and are hearty eaters: NLS flake, Spirulina pellet, cichlid pellet, freeze-dried black-worms with spirulina, frozen blood-worms.
This tank gets 2- 50% water changes weekly as geophagus and biotodoma sp. require a pristine water quality, like discus.
Im sure the Lemons dont require such a frequent water changing schedule, but they have certainly benefited from it.
As far as temperament, they are very docile to one another, rarely do i see any con-specific aggression-- some light chasing occasionally.
This is the tank they are in:
Wasn't sure if you wanted info on the African tetras-- i certainly can add some info on them as well if you like.
