This species is notoriously aggressive with a reputation for biting the fins of other fishes, although this behaviour only seems to be pronounced when insufficient numbers are purchased or space is limited.
That said, it is relatively boisterous and does not make an ideal companion for timid, slow-moving, or long-finned species such as many livebearers, cichlids, and anabantoids.
Robust fishes inhabiting similar biotopes in nature, especially comparably-sized, pelagic cyprinids perhaps constitute the best choices but other options include balitorid, cobitid, and nemacheilid loaches as well as benthic cyprinids such as Crossocheilus or Garra species. If geography is not an issue many rainbowfishes and tetras are also suitable, but be sure to research your choices thoroughly before purchase.
It is a gregarious species forming loose hierarchies, with rival males continually battling with each other for female attention and hierarchical position within the group.
A group of at least 8-10 specimens should be considered the minimum purchase since this increases the likelihood that the fish will be distracted by each other rather than their tankmates and will result in a more natural-looking display. Males will also show better colouration in the presence of conspecific rivals.
