The Buenos Aires Tetra can be housed in an aquarium with other soft water fish. Tetras are a schooling fish that work well in groups of six or more fish of the same species. Artificial plants, rocks, and driftwood help to enhance its natural habitat and provide hiding spaces. The Buenos Aires Tetra will eat most live plants, except Java Fern.
Buenos Aires Tetras breed occasionally in an aquarium setting and a hospital or "breeding tank" will be necessary. Slightly acidic water is best for optimal breeding habits. After the eggs begin to hatch, removing the parents will reduce the number of lost fry.
The Buenos Aires Tetra will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, and a high-quality flake food.
