Sandy habitats at moderately deep levels, generally deeper
than 15 m.
Geographic distribution:
North-western Lake Malawi, including Mdoka, Chesese and
Chirwa Island. Most aquarium specimens originate
from Mdoka.
Typical adult size:
Wild size not precisely documented; imported males measure
about 12–15 cm TL and may exceed 20 cm TL
in long-term aquarium conditions.
Sexual dimorphism:
Sexual dichromatism is absent. Males grow larger than
females and develop longer fins and a more
pronounced mouth. Older females may lose the
intense blue coloration and appear pale.
Recommended aquarium size:
A minimum aquarium volume of 500 l is recommended for
a group of 5–6 individuals. In mixed tanks with
large sand-foraging species, 800–1000 l is
required.
Aquarium setup:
Provide extensive open sand areas with limited rockwork.
Water should be clean, well filtered and strongly
oxygenated, with a pH around 7.8–8 and a
temperature near 25 °C. The species is sensitive
to poor water quality and benefits from frequent,
moderate feeding rather than large meals.
Diet:
Feeds by hovering above sand and collecting edible
particles, often exploiting sediment disturbed by
large sand-foraging genera such as
Taeniolethrinops and Fossorochromis.
In aquaria it accepts small frozen foods such as
Artemia and Cyclops, supplemented with quality
dry foods.
Breeding:
Maternal mouthbrooder. Males select a sheltered site and
court females with display movements before
spawning. Eggs are collected and incubated in the
female’s mouth for about 3 weeks at 25 °C.
Fry are released gradually once the female
perceives sufficient safety.
Aggression:
Quarrelsome mainly toward conspecific males, but serious
damage is uncommon due to relatively weak bites.
Males engage in frequent mouth contests.
Special notes:
Recognized by its deep blue coloration and distinct white
snout tip. Juveniles show a barred pattern similar
to members of the P. electra group. Evaluated
as Endangered (EN) on the IUCN Red List (2018).
Sexual dichromatism is absent, which is unusual
among haplochromines.
