The details of aquarium maintenance for all three species are more or less identical: the rummy-nose tetra is a schooling fish, which exhibits tight schooling behaviour both in the wild and in the aquarium. Consequently, these fishes should be maintained in groups of no fewer than six individuals, with larger numbers being preferable where space permits-these tetras preferring about a 25 gallon/80 litre aquarium. All three species are lovers of warm aquarium water, the temperature range for maintenance being 24 °C to 31 °C, with the fishes sometimes requiring temperatures as high as 33 °C for breeding. Consequently, compatibility of these fishes with cooler water fishes is contra-indicated: for example, panda corydoras would be a bad choice of companion as these fishes prefer lower temperatures, and there is little overlap in the temperature ranges of the two species. Many fish can be kept with rummy-nose tetras, some including smaller gourami, tetras, barbs, danios, Australian rainbows, and various catfish, such as Ancistrus. The rummy-nose tetra cannot be kept with other popular ornamental fishes, such as African cichlids, as they occupy very different water parameters.
