Very peaceful making it an ideal resident of the well-researched community aquarium.
It is best-maintained alongside similarly-sized characids, gasteropelecids, lebiasinids, smaller callichthyid or loricariid catfishes and non-predatory, small-to-medium-sized cichlids.
Try to buy a mixed-sex group of at least 8-10 specimens, include other schooling fishes to provide security, and you will be rewarded with a more natural-looking spectacle.
