Intermediate habitat; recorded at depths of 3–15 m.
Geographic distribution:
East coast of Lake Malawi in Tanzania, between the Ruhuhu
River and Ikombe.
Typical adult size:
Up to 16–18 cm total length.
Sexual dimorphism:
Males are larger and more colorful. Females remain silvery with shorter
fins; dominated or non-breeding males can resemble females but are usually
larger.
Recommended aquarium size:
A minimum aquarium volume of 400 L is recommended, preferably more
than 600 L.
Diet:
Primarily bottom-dwelling invertebrates and other soft-bodied
invertebrates sifted from sand by pushing the snout into the substrate.
Breeding:
Maternal mouth-brooder. Breeds year-round, mainly from August to January.
Territorial males dig shallow bowls or small semicircular sand-scrape pits
against rocks and court females around the site. Eggs are collected in the
female’s mouth and fertilized during spawning; incubation lasts about three
weeks, and fry are released over the following week.
Aggression:
Generally not aggressive among Malawi haplochromines and is usually not
dominant in a Malawi aquarium.
Special notes:
Both sexes and juveniles show the genus-typical dark diagonal band from
the nape to the caudal peduncle; in some individuals the band is interrupted
in several places. The head is pointed with strongly developed lips, and
females are darker in coloration compared to populations south of the
Ruhuhu River. On our website tanganyika.si this form is treated as a
distinct species under the name Mylochromis sp. 'mchuse'. Ad Konings
considers these northern populations a geographical variant of
Mylochromis sp. 'lateristriga makanjila'.
