SynopsisTilapia rendalli of Lake Malawi dig large tunnels in their nests and practise communal care of young. Both these traits are considered to be antipredator adaptations. 
The effect of environmental factors on the nesting and courtship behaviour ofTilapia zillii in Lake Kinneret (Israel)
Tilapia zillii is a polyphilic, guarding nest spawner which is widespread in west and north Africa and in the Middle East. A study of the nesting and courtship behaviour of this species in Lake
Interspecific brood-mixing in Tanganyikan cichlids
It is concluded that adoption of young before independence results from farming-out, a behavior by which parents actively transfer their young to foster parents.
Fish communities in the African Great Lakes
Biodiversities in the littoral/sublittoral zones of the very ancient, deep, clear, permanently stratified rift lakes Tanganyika and Malawi are contrasted with the simpler systems in their pelagic zones, also with biodiversity in the much younger, shallower Victoria, the world's largest tropical lake.

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.
No effect of anthropogenic food provisioning and population density on the aggressive behavior of a territorial Cichlid: a case study
Food provisioning for fish is a very common leisure activity, especially in tourist attractions, causing impacts that are still poorly understood. There are many species of territorial fish to whom

SynopsisThe guild concept is explained to represent peaks in the landscape of reproductive styles, which respond to the ‘altricial ⇄ precocial principle’ caused by the processes of heterochrony and
Cichlid-catfish mutualistic defense of young in Lake Malawi, Africa
It is concluded that the parental catfish increase the survival of their own young be allowing cichlids into the brood, because of an asymmetry of costs between the two species.
Formation of the selfish school
The findings support the predation dilution and geometrical design hypotheses of the selfish school model previously proposed by McKaye & Oliver (1980).
Alloparental care in fishes
Broad patterns of known examples of alloparental care are described, the pathways to adoption are highlighted, and the ways in whichalloparents derive fitness benefits are highlighted.


Ethology and ecology of cichlid fishes of the genus Etroplus in Sri Lanka: preliminary findings
Asian cichlid fishes, Etroplus maculatus ( Bloch) and E. suratensis (Bloch) were observed in their natural habitat and displays a unique behavior during its parental cycle where both parents actively defend their young until they are nearly sexually mature and almost the size of the parents.
Reproductive Guilds of Fishes: A Proposal and Definition
Thirty-two guilds putatively encompass all living fishes, based mainly on form and function in early developmental intervals, on preferred spawning grounds, and on features of reproductive behavior, based on an earlier concept of ecological groups.
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.
