Under natural circumstances, I have never observed fights, neither in A. auditor nor in Chitande Type Aulonocara . In the aquarium, however, fights may occur. Territorial males live rather far apart in the wild and remain very static. The territory of a male A. auditor usually lies on the sand between some stones or rocks. They were found only at the edge of the rocky habitat.
Females occur in large schools and forage over the sand.
Within such schools males with faint breeding colors were observed. No territories were defended within the schools although the school and its members remained rather static. Other species of Aulonocara were found in the schools together with A. auditor . Besides two different sand dwelling species, A. rostratum and A. sp. Ngara and Mdoka are the only two locations where two different species of the Chitande Type Aulonocara group are sympatric.
