Near Tembwe, approximately 40 km south of Moba,
Lake Tanganyika, DR Congo
Biotope:
Open water along deep rocky shores at depths of approximately
25–45 m. Occurs in large schools, often numbering hundreds or
thousands of individuals. In mixed Cyprichromis schools,
Cyprichromis pavo typically occupies the lower part of
the shoal. Frequently found together with
Cyprichromis leptosoma, C. sp. 'leptosoma jumbo',
Paracyprichromis nigripinnis and P. brieni.
Geographic distribution:
Endemic to Lake Tanganyika. Occurs in the southern half of the lake.
On the western shore (DR Congo) found south of Kanoni, while on the
eastern shore (Tanzania) found south of Luagala Point. Present along
the entire Zambian shoreline. In the Mahale Mountains area in
Tanzania, between Sibwesa and Luagala Point, it occurs sympatrically
with the otherwise northern species Cyprichromis microlepidotus.
Typical adult size:
Males reach up to approximately 12 cm total length.
Females are only slightly smaller, around 11 cm.
Sexual dimorphism:
Males are slightly larger and more colourful than females.
Females are beige to light brown. Males exhibit pronounced
polychromatism.
Recommended aquarium size:
Minimum 350 L
Aquarium setup:
Provide ample open swimming space with only a limited number of
rocks. Substrate choice is not critical, as the species does not
feed or spawn on the bottom. Best kept in schools of at least
10 individuals. Prefers a relatively dim aquarium with subdued
lighting, reflecting its deep-water habitat.
Diet:
Carnivorous planktivore. Feeds primarily on zooplankton in the
wild, occasionally supplemented by small invertebrates when
plankton availability is low.
Breeding:
Maternal mouthbrooder. Breeding behaviour differs from most other
Cyprichromis species. Males do not maintain a
three-dimensional territory in open water, but instead defend
a territory adjacent to a vertical rock surface. The male lures
a female away from the shoal to this site, where spawning occurs
on or near the rock. Eggs are fertilised and immediately collected
by the female. Clutch size is typically 5–12 eggs. Incubation
lasts approximately four weeks.
Aggression:
Relatively peaceful species, suitable for community aquaria with
various sand-dwelling Tanganyikan cichlids.
Special notes:
Cyprichromis pavo differs from
C. microlepidotus by its southern distribution,
longer ventral fins, and distinct breeding behaviour.
Despite its wide distribution, no strongly distinct geographical
variants are known. A slight variation is observed in northern
Tanzanian populations, where males may show a yellowish dorsal fin,
while males from most other populations have a bluish dorsal fin.
Males are polychromatic; however, unlike most other
Cyprichromis species, it is the anal fin (rather than the
caudal fin) that may be yellow or blue. Females are uniformly beige
to light brown.
A key diagnostic feature of C. pavo is the presence of a
higher number of smaller scales on the flank compared to other
Cyprichromis species.
