Ectodini is a tribe of cichlids that are endemic to Lake Tanganyika in East Africa. They live in the benthic zone. Most of the genera in this tribe are monotypic. These fishes show diverse morphology and behaviour and the tribe includes taxa which live in sandy, muddy and rocky habitats.

Ancistrini is a tribe of catfishes of the family Loricariidae. Most are restricted to tropical and subtropical South America, but there are also several genus (Ancistrus, Chaetostoma, Hemiancistrus and Lasiancistrus) in southern Central America.

Chromidotilapiini is a tribe of small cichlids from tropical West and Middle Africa. There are thirteen genera and over fifty described species in this tribe.

Limnochromini is a tribe of African cichlids from Lake Tanganyika. They are bi-parental and mouthbrooding fish.

Lamprologini is a tribe of African cichlid fishes. It contains seven genera and nearly 100 species. Over half of the species in this tribe are in the large genus Neolamprologus. Most genera in the tribe are endemic to Lake Tanganyika, but one species of Neolamprologus (N. devosi) is from the Malagarasi River in Tanzania, and several species of Lamprologus are from the Congo River Basin.

Geophagini is a tribe of cichlids from the subfamily Cichlinae, the American cichlids. It is the sister taxon to the clade which includes the Cichlasomatini and Heroini. Fishes in the Geophagini are distributed from Panama south to Argentina, it is the most speciose of the seven tribes within the Cichlinae and it is subdivided into three sub-tribes, Acarichthyina, Crenicaratina, and Geophagina which together contain over 200 species. Geophagines show morphological and behavioural specialisations to enable them to sift the substrates within their mouths so that they can separate benthic inverte

Tropheini is a tribe of African cichlids, endemic to Lake Tanganyika. The species in this tribe are mouthbrooders.

Cyprichromini is a tribe of African cichlids, containing seven species in two genera: Cyprichromis and Paracyprichromis. Most of the species are endemic to Lake Tanganyika; only C. microlepidotus has also been seen in eastern Tanzania.

Heroini is a fish tribe from the Cichlasomatinae subfamily in the family Cichlidae (cichlids). All cichlids native to the Greater Antilles, United States (southern Texas), Mexico and northern Central America are members of this tribe. It also includes most cichlid species in southern Central America (where the only non-Heroini cichlids are Andinoacara and Geophagus) and several species from South America (where several other tribes exist). A large percentage of its species were formerly placed in the genus Cichlasoma (itself now placed in the tribe Cichlasomatini) but have since been moved to

Hemichromini is a tribe of African cichlids. The group consists of 14 species of freshwater fish from two genera: one species in Anomalochromis and the remaining in Hemichromis.
