SynopsisOf 23 males and 39 females of Plecodus straeleni observed for one hour each, 2 males and 14 females searched for the mouthbrooder Cyathopharynx furcifer under courtship display near or in the bower to get eggs, besides foraging for other prey to ripe off scales and skin. After finding a courting C. furcifer, they quietly waited on the substrate near the bower until it spawned. Immediately after spawning, the waiting P. straeleni dashed upon the female of C. furcifer and quickly… 
Foraging behavior of the scale-eater Plecodus straeleni (Cichlidae, Teleostei) in Lake Tanganyika, Africa
TLDR
Hunting techniques and prey preference varied not only with sex and size but even among consexuals of similar sizes and a number of individuals successively attacked only one or a few prey species in 1 h.
Polychromatism of the scale-eaterPerissodus microlepis (Cichlidae, Teleostei) in relation to foraging behavior
TLDR
Differences in body coloration were found among adult and subadult individuals, which were classified into 4 color morphs designated as Beige, Dark, Grey and Stripe, which differed from other morphs.
Tactic for bower acquisition by male cichlids,Cyathopharynx furcifer, in Lake Tanganyika
  • K. Karino

TLDR
Waiting for bower desertion by other males may be the best bower acquisition tactic for males without bowers.
Female mate preference for males having long and symmetric fins in the bower-holding cichlid Cyathopharynx furcifer
TLDR
Bower size did not correlate with male reproductive success in C. furcifer, and female choice may be dependent instead on males having long and symmetrical pelvic fins apparent during the circling behaviour carried out in the bowers.
Reproductive parasitism: male and female responses to conspecific and heterospecific intrusions at spawning in a mouth-brooding cichlid Ophthalmotilapia ventralis.
TLDR
A rare form of alternative reproductive behaviour without simultaneous parasitic spawning was observed in Ophthalmotilapia ventralis, a lekking mouth-brooding cichlid from Lake Tanganyika, and female responsiveness to bourgeois male courtship tended to decline when floaters were present.
Trophic interrelationships amongst cichlid fishes in a tropical African reservoir (Lake Chivero, Zimbabwe)
TLDR
The diet of seven cichlid species of Lake Chivero, Zimbabwe, was investigated from October 2004 to April 2005 to determine the degree of dietary overlap and interspecific competition, which indicated changes in the lake, which is eutrophic and has experienced severe algal blooms since 1960.
Variations in the breeding behavior of cichlids and the evolution of the multi-functional seminal plasma protein, seminal plasma glycoprotein 120
TLDR
Results suggest that SPP120 might be associated with oral fertilization, and reproductive traits that define the interaction between sperms and eggs could be the evolutionary selective force that cause the rapid functional modification of the fertilization-related reproductive protein, SPP 120.
Evolution of egg dummies in Tanganyikan cichlid fishes: the roles of parental care and sexual selection
TLDR
Investigating how mouthbrooding and egg dummies have evolved in Tanganyikan cichlids, the lineage which seeded the other African radiations, provides evidence supporting the hypothesis of egg dummy evolving through sensory exploitation and highlights the role of sexual selection in favouring the evolution and maintenance of this trait.
Bower‐building behaviour is associated with increased sperm longevity in Tanganyikan cichlids
TLDR
The results indicate that the extension of sperm longevity as a result of the emergence of bower builders may have acted as an evolutionary attractor for sperm longevity, whereas sperm competition rank does not play a major role.
Predators, reproductive parasites, and the persistence of poor males on leks
TLDR
Several game-theoretic models are presented that show that avoidance of costly and mobile predators, sneakers, or brood parasites (enemies) leads to variation in female choice, which can result in maintenance of variation in male quality.

TLDR
Reproductive ecology and ethology of 52 cichlid fishes were studied along the shore of Myako, east-middle coast of Lake Tanganyika and the relationship between parentalcare patterns and mating systems within the family Cichlidae are discussed.
Sexual dichromatism and feeding habits of the scale-eaterPlecodus straeleni (Cichlidae, Teleostei) in Lake Tanganyika
TLDR
To understand this species' colour variation, 52 specimens were captured with a gill net at a depth of 328 m and examined their external morphology and gonads in the laboratory to know the relationship between colour and food habits.
THE DISPUTED FEEDING BEHAVIOUR OF A PAEDOPHAGOUS HAPLOCHROMINE CICHLID (PISCES) OBSERVED AND DISCUSSED
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
In Lake Tanganyika, an endemic mochokid catfish, Synodontis multipunctatus Boulenger, is a brood parasite of mouthbrooding fishes of the family Cichlidae, and the early stages of development of this catfish not only depend upon their hosts for food and protection, but exploit almost their entire parental investment.

TLDR
The evolution of advanced hiding styles in reproductive guilds of fishes is discussed and ends with a speculation that the Latimeria, having had more geological time to refine its hiding style, releases fully developed young, 25 to 30% the size of the adult fish.
