Sediment-free rocky habitat on steep shores,
remaining in mid-water about 1 m from the substrate
and usually within the upper 5 m below the surface.
Geographic distribution:
Western shore of Lake Malawi and northeastern coast
at Magunga and Lupingu, extending south of Minos Reef
along the eastern shore.
Typical adult size:
Males up to about 20 cm total length;
females up to approximately 16 cm.
Sexual dimorphism:
Males develop breeding coloration and defend territories in open water.
Females remain smaller and less intensely colored.
Aquarium setup:
Provide ample swimming space and rocky structures with caves.
Only one adult male per aquarium is recommended.
Diet:
Carnivorous; feeds on insects and soft-bodied invertebrates
that fall or are washed into the water.
Forms small mid-water feeding schools and also consumes plankton when available.
Breeding:
Males defend open-water territories in the upper 5 m,
but spawning occurs in caves within the rocky substrate.
Females are courted in open water and led to the spawning cave.
Aggression:
Less aggressive than some other Protomelas species,
but males are territorial and respond strongly to similar-looking species.
Special notes:
Distinguished by large dark spots along the base of the dorsal fin,
larger than those of the dorso-lateral band.
Member of the P. spilonotus group, which includes closely related,
geographically separated forms with similar behavior and niche occupation.
