A male Pseudotropheus "aggressive yellow head" photographed
underwater at Maleri Island. Yet another Pseudotropheus "aggressive"
species, this one is reported only from the Maleri group, where
Ribbink and colleagues reported it to occur at depths between 2 m and 18 m,
most frequently at 5-10 m where it was common. "Both sexes are
aggressively territorial and will chase most intruders. Algal gardens
were found in about 20% of the territories. Nests are occasionally
excavated alongside rocks, but usually the fishes tunnel beneath rocks.
Two mouth-brooding females were seen defending territories which
suggests that they leave their territories to spawn, and resume
territoriality thereafter" (Ribbink et al., 1983: 192).
