This speciesis notoriously aggressive with a reputation for bitingthe fins ofother 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 notmake an ideal companion for timid, slow-moving, or long-finned speciessuch as many livebearers, cichlids, and anabantoids.

Robust fishesinhabiting similar biotopes in nature, especially comparably-sized, pelagiccyprinids perhaps constitute the best choices but other options include balitorid, cobitid, and nemacheilid loachesas well as benthic cyprinids such asCrossocheilusorGarraspecies.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 purchasesince this increases the likelihood that the fish will be distracted by each other rather than their tankmatesand willresult in a more natural-looking display.Males will also show better colouration in the presence of conspecific rivals.
