Obligate feeding of cichlid eggs by Caecomastacembelus zebratus in Lake Tanganyika
TLDR
Examination of food habits of four common species of spiny eels in Lake Tanganyika found that Caecomastacembelus zebratus is an obligate egg-eater and one of the predators that cause the high mortality of early cichlid broods.
Occasional egg-eating by the scale-eater Plecodus straeleni (Cichlidae) of Lake Tanganyika
TLDR
This egg-eating was achieved 5 times by 3 females who spent most of their time searching and waiting, besides foraging for other prey to ripe off scales and skin.
Alternative life-history styles of some African cichlid fishes

TLDR
Trends which provide an insight into cichlid life histories, into evolutionary alternatives and into behavioural alternatives which may be followed during the life time of these fishes are emerging are emerging.
Microsatellite variation demonstrates multiple paternity in lekking cichlid fishes from Lake Malawi, Africa
TLDR
The low heterozygosity of a Melanochromis auratus brood is consistent with reduced levels of mtDNA polymorphism previously documented in this species, suggesting microsatellite variation may provide insight into the genetic history of these populations.
Grasping ecological opportunities: not one but five paedophagous species of Haplochromis (Teleostei: Cichlidae) in the Lake Edward system
TLDR
A morphometrical revision of all species of Haplochromis from this system with a morphology that suggests a paedophagous diet is performed, revealing the presence of three new species: H. gracilifur sp.
Protomelas krampus, a new paedophagous cichlid from Lake Malawi (Teleostei, Cichlidae)
A new paedophagous species of Protomelas , P. krampus sp. nov., is described from Lake Malawi. It has been found in Lukoma Bay in Tanzania, near Mara Point in Mozambique, and at Otter Point,
14 Cichlid Fish Diversity and Speciation
TLDR
Their highly integrated pharyngeal jaw apparatus permits cichlids to transport and process food, thus enabling the oral jaws to develop specialisations for acquiring a variety of food items.
Trophic eggs and parental foraging for young by the catfish Bagrus meridionalis of Lake Malawi, Africa
TLDR
Parental bagrid catfish in Lake Malawi, Africa, appear to feed their young in a manner analogous to birds and social insects, and indirect evidence suggests that the male leaves the nest to forage and returns with benthic invertebrates in its mouth that are fed to the brood.
Playing out Liem’s Paradox: Opportunistic Piscivory across Lake Tanganyikan Cichlids
TLDR
Evidence is provided for cichlid species acting as jacks-of-all-trades in Lake Tanganyika and this evidence is discussed in the framework of Liem’s classic paradox: that trophic specialization does not preclude dietary flexibility.
The reproductive biology of an open-water spawning Lake Malawi cichlid, Copadichromis chrysonotus
TLDR
Length at maturity, sexual dimorphism, spawning behaviour, breeding seasonality, fecundity, fertility, egg size, and brooding habits of C. chrysonotus in southern Lake Malawi are investigated.

TLDR
Considering morphological information from various authors, snout-engulfing may be a widespread technique among the "larger mouthed" paedophages (i. e. in Lake Victoria: 6 out of 8 spp. described plus at least 8 new spp.).

TLDR
Lower vertebrates have not evolved cooperative nursery groups of the kind that constitute the building blocks of mammalian societies, and for other reasons possibly the lack of haplodiploid sex determination or the presence of the right ecological imperatives, they have not become altruistic enough to generate insectlike societies.
