The males can show 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.
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 small moluscs, insect larvae, and micro-organisms so a diet including flakes, mysis shrimp, daphnia, mosquito larvae, live baby brine shrimp, and cyclops is recommended.
