A relatively hardy species which is suitable for medium-large sized aquariums with other robust fish. In smaller aquariums, they may bully smaller shy species and will nip at long flowing fins. This is a shoaling species which should be kept in groups of 6 or more. Buenos Aires Tetras relish live plants, so they are not recommended for planted aquaria as anything green and leafy will be regarded as a food source. An albino or gold variety is also available.
An omnivorous species which will eagerly accept most foods offered e.g. flake, green flake, small pellet foods, a huge variety of frozen foods, and vegetable matter.
Fairly easy to breed in a dedicated softwater breeding aquarium. The aquarium should be as spacious as possible, as Buenos Aires Tetras are very active during spawning. The spawning takes place over fine-leaved plants, and the parent fish should be removed once the female is exhausted of eggs. After 24 hours, the eggs will hatch.
