During the dry season and period of low water, this species is found in pools and ponds with more or less stagnant water. In February, water data collected at the type locality has pH 7.9; electrical conductivity 240 μS/cm; temperature 24.2 °C. Associated fish fauna included Phalloceros caudimaculatus (Poeciliidae), Rineloricaria sp. (Loricariidae) and two small characid species. This species displays a variety of parental care and mating systems ranging from mouthbrooding and polygyny to substrate spawning and monogamy. In the aquarium, breeding was observed and the species was azuensis found to be a delayed (larvophile) maternal mouthbrooder, where like several of its congeners, it starts reproduction like a substrate spawner, i. e. the parents initially spawn on a stone, but just prior to the hatching of the larvae the female picks up the eggs and then orally broods the larvae and young. Courting males, in from of ripe females, display a conspicuous quivering movement of their mouths caused by opening and closing the mouth with extremely high frequency and this peculiar behaviour during courtship seems to be a synapomorphy of the mouthbrooding species, as it has been observed only within this species complex (Ref. 78439).
