Maylandia flavifemina 'Thumbi West Island' Metriaclima flavifemina 'Thumbi West Island'
Genus:
Maylandia
Type locality:
Maleri Island, Lake Malawi, Malawi.
Biotope:
Rocky habitat, mainly in intermediate zones around islands at depths of 5–40 m (most common around
~15 m). At Chidunga Rocks it is most common near the bottom of the reef at about 6 m.
Geographic distribution:
Occurs at all three Maleri Islands (Maleri, Nakantenga, Nankoma), at Thumbi West Island, at
Chidunga Rocks and at Namalenje Island.
Typical adult size:
In the wild, males reach about 10 cm total length and females about 9 cm; in
aquaria males may grow to 16 cm or more.
Sexual dimorphism:
Adult males are blue with black bars and variable black markings in the dorsal fin, often
including a dark submarginal band (some Thumbi West males may lack a clear submarginal band but show other
black streaks/spots). Females differ by population: Maleri and Chidunga females are mainly yellow, while
Thumbi West and Nakantenga females are beige with a bright yellow anal fin. Juveniles and females are
light blue-beige to yellow with a bright yellow anal fin; males have a black anal fin and black membranes
in the caudal fin.
Recommended aquarium size:
250 L.
Aquarium setup:
Provide extensive rockwork with many caves and hiding places. Keep one male with 3–4 females.
Diet:
Herbivorous. Diet in the wild can include invertebrates
and plankton in addition to loose aufwuchs, especially in deeper, sediment-influenced habitats.
Breeding:
Breeding males are territorial, usually holding spaces between rocks (often with a sandy bottom)
and may burrow beneath a rock to create a spawning cave. Females are often solitary or in small groups and
are courted near a male’s territory. Spawning occurs inside the male’s burrow. Females are maternal
mouthbrooders; broods typically number 10–30 eggs, with release after about three to three and a half
weeks, followed by abandonment.
Aggression:
Aggressive within the species; generally tolerant toward other species.
Special notes:
Part of Ad Konings’ “black-dorsal group” (with M. lundoensis, M. nigrodorsalis, M. phaeos and
M. sp. ‘black dorsal mbenji’; also associated with M. sp. ‘msobo’ and M. sp. ‘msobo heteropictus’). It was
formerly known in the hobby as Maylandia sp. ‘black dorsal’.
