Aulonocara gertrudae

The habitat of Aulonocara gertrudae varies between populations, those south of the Ruhuhu River are sand dwellers which exploit the sandy muddy substrates found near river mouths, while those to the north of the Ruhuhu will occupy rocky habitats too. The territorial males of this species excavate a burrow in the sand or they may use a cavity formed in a rocky area, especially in the northern populations. The females are found in small foraging groups in the vicinity of the males.
