Pseudotropheus sp. 'socolofi nkolongwe' Nkolongwe
Genus: Pseudotropheus
Biotope: Very shallow intermediate habitat, found at depths no greater than about 3 m; males defend holes dug under and between rocks.
Geographic distribution: Only known from the southeastern coast of Lake Malawi in Mozambique, around Nkolongwe.
Typical adult size: Around 10 cm total length.
Sexual dimorphism: Males are larger than females, with broader fins and larger anal ocelli; males are plain sky blue, while females are duller grey-blue.
Diet: Anterior tooth shape indicates adaptation to algae pulling; likely feeds mainly on aufwuchs and possibly small invertebrates. In captivity, feeding should be sparing and mainly herbivorous to prevent obesity and intestinal disorders.
Breeding: Maternal mouthbrooder; eggs and fry are incubated for about 3 weeks, with release occurring within about one week depending on conditions.
Aggression: Strongly territorial; males actively chase conspecific intruders from their territories, though generally less dangerous to tank mates than some other highly aggressive mbuna.
Special notes: Recognizable by the plain sky-blue coloration of adult males and a stretched, rectangular body profile. Differs from the zebra complex by body shape and from Pseudotropheus socolofi by a broader mouth and strongly concave snout. Jaws are strong and protruding, bearing densely set bicuspid teeth; males show a yellow-orange hint on the throat.
