A spectacular fish, the males can show particularly strong conspecific aggression, with members of the same sex being hounded through the whole tank. Females will also be hounded, but less so then males. It is recommended to keep a single male, to four to six females because of this, and some cover for the females to escape the males. This aggression rarely leads to damage, even with males, but relentless chasing can lead to the weaker fishes demise though exhaustion.
It is noted that tank raised specimens are somewhat less persistent in their chasing then wild caught ones are.
In the wild, they dine on insect larvae and small crustaceans, so a diet including flakes, mysis shrimp, daphnia, mosquito larvae, live baby brine shrimp, and cyclops is recommended.
