Maylandia pyrsonotos X Maylandia zebra 'Makanjila Rocks'
Genus:
Maylandia
Type locality:
Nankantenga Island (Maleri Island), Lake Malawi, Malawi
Biotope:
Rocky habitat. The species is strictly associated with rocks, usually occupying
large rocky structures and crevices, generally not occurring shallower than about
5 m and extending down to approximately 20 m depth.
Geographic distribution:
Southern part of Lake Malawi, where it occurs at Nakantenga Island, Nankoma Island,
Kanchedza Island, Nkhudzi, Mphande Island and Chimwalani Reef. Populations formerly
known as Maylandia thapsinogen (Chimwalani Reef) and Maylandia sandaracinos
(Nkhudzi and Mphande Island) are now regarded as junior synonyms of
Maylandia pyrsonotos.
Typical adult size:
In the wild, males reach about 10 cm total length and females about 8 cm. In
aquarium conditions, both sexes may grow considerably larger, commonly reaching
13–15 cm.
Sexual dimorphism:
Males are blue with distinct black vertical bars and a yellow to orange dorsal fin,
while females are light brown to greyish with faint bars and a yellowish dorsal fin.
In some populations, males may also show a yellow throat.
Recommended aquarium size:
At least 400 liters for a community aquarium; smaller setups are only suitable for
a single male with several females.
Aquarium setup:
An aquarium with a high number of rocks and shelters is required. Territories are
centered around caves or rock crevices used for spawning. Stocking is best based on
one male with at least three to four females to limit aggression.
Diet:
Herbivorous, feeding mainly on Aufwuchs scraped from rocky substrates, consisting
largely of algae, diatoms and associated material. In the wild, plankton may also
form a significant part of the diet.
Breeding:
Maternal mouthbrooder. Breeding males defend territories centered around caves among
rocks. Spawning takes place inside the male’s territory, after which the female
incubates the eggs in her mouth for approximately three to three and a half weeks
before releasing the free-swimming fry.
Aggression:
Aggressive toward conspecifics, especially between males, but generally tolerant
toward other mbuna species when adequate space and structure are provided.
Special notes:
This species belongs to the group commonly referred to as red-top zebras and is
closely related to several taxa that were previously regarded as distinct species.
Genetic and morphological studies have shown that populations once described as
Maylandia thapsinogen and Maylandia sandaracinos represent the same species
and are now treated as junior synonyms of Maylandia pyrsonotos. A similar-looking
population at Makanjila Rocks was shown by DNA analysis to be a natural hybrid
between Maylandia zebra males from north of Makanjila Point and
Maylandia pyrsonotos females from Chimwalani Reef.
