25b. Perchlike fishes (2): Cichlids from the Great African Lakes (52)

  • Pseudotropheus sp. “Acei” White Tail Ngara

    30. October 2020

    Where does a species start, where does the location variant end? This question is really difficult to answer for some groups of fish, e.g. killies and cichlids from Lake Malawi and Lake Tanganyika. In the case of Pseudotropheus sp. “Acei” from Lake Malawi, the species is not described scientifically. Mostly the light blue, yellow-fin “Acei” […]

  • Aulonocara maylandi

    5. October 2020

    The sulphur head aulonocara, Aulonocara maylandi, is one of the most peaceful species of Malawi cichlids. The species reaches a maximum length of 12 cm (male) and 10 cm (female). In the wild these fish only live in two reefs of the south-eastern Lake Malawi, namely Chimwalani Reef (formerly Eccles Reef) and Luwala Reef (formerly […]

  • Nimbochromis livingstonii

    21. February 2020

    The genus Nimbochromis is probably best known to aquarists through the “sleeper”, N. livingstonii. All Nimbochromis species have a camouflage pattern of irregular brown spots. N. livingstonii uses this to imitate a decaying fish, because fish carrion look very similarly spotted. So the sleeper lies on his side on the ground and plays dead fish. […]

  • Tropheus duboisi

    21. October 2019

    Tropheus duboisi are the “somewhat different” Tropheus. While the remaining species of the genus Tropheus are hectic, in groups living, always quarreling swimmers, T. duboisi are at least in the nature rather singulary living fish, who are found occasionally also in pairs. They are clearly calmer and also considerably less aggressive than the other Tropheus. […]

  • Lamprologus brevis Kapampa

    7. October 2019

    Many cichlids from Lake Tanganyika have different local populations that also look more or lress different. The snail cichlid Lamprologus brevis (sometimes also called Neolamprologus brevis, the species belongs neither to one nor to the other genus, but to a genus still to be described) has a lake wide distribution and therefore it has become […]

  • Nimbochromis venustus

    30. August 2019

    The genus Nimbochromis is probably best known to the aquarists through the “sleeper”, N. livingstonii. All species of Nimbochromis have a Camouflage pattern from irregular, brown spots. N. livingstonii uses this to mimic a decomposing fish, because fish carrion looks very similarly patchy. So the sleeper lies on his side on the ground and plays […]

  • Tropheus sp. “Phoenix”

    28. June 2019

    The cichlids of the genus Tropheus are widespread around the gigantic Lake Tanganyika in numerous locality-variants. The sometimes very different looking animals testify to rising and sinking water levels over the millennia. As strict Aufwuchs eaters, Tropheus cichlids are not able to migrate over larger sandy areas and so the stone reefs of the lake […]

  • Pseudotropheus sp. “Acei”

    22. May 2019

    It is hard to understand why such a well-defined and unique species has not yet been scientifically described, although the animals have been kept and bred in the aquarium for decades. And yet it is; “Acei” is a pure popular name and not a scientific name. The species can be found in several different coloured […]

  • Callochromis pleurospilus “Kigoma”

    15. May 2019

    This sand cichlid originates from Lake Tanganyika, where it is found almost all over the lake with the exception of the extreme south. Our animals are descendands from fish that were collected at Kigoma Bay; fully coloured males (unfortunately our quite young, 4-6 cm long animals do not show this yet) of this local variant […]

  • Haplochromis sp. “Thick Skin” (CH44)

    3. May 2019

    Unfortunately many Haplochromis-like cichlids of Lake Victoria are threatened by extinction due to profound environmental changes. The giant perch (Lates niloticus) introduced there, the turbidity of the water due to eutrophication and the resulting mass growth of the water hyacinth (Eichhornia crassipes) are the best known causes. For this reason, a conservation breeding programme is […]
