Mwaya or the Mbasi River mouth, north end of Lake Malawi, Tanzania
Biotope:
Gradually sloping sandy bottoms, including breeding leks
established on open sand at depths of approximately 3–6 m.
Geographic distribution:
Northern half of Lake Malawi.
Typical adult size:
Up to about 18 cm total length.
Aquarium setup:
Requires extensive open sandy substrate to allow males to
construct sand turrets used as spawning sites.
Breeding:
Males build sand turrets on open sand, forming breeding
leks in which 20–30 males may be spaced several meters apart.
The spawning structure is similar in general form to that of
N. microcephalus but larger and less strongly slanted.
Aggression:
Territorial during the breeding season, with males
defending their individual sand turrets within the lek.
Special notes:
One of the larger members of the genus. The breeding
structures are comparable to those of N. microcephalus but
differ in size and inclination.
