These fossils are from a Late Miocene marine deposit and a Middle Pleistocene nonmarine deposit, and do shed some light on ideas about cichlid
paleobio-geography in the New World.
What happens if such a territorial cichlid
fish is castrated?
76) were lower than those registered by Chukwuemeka, Tsadu, Ayanwale, Erhabor, and Falusi (2014) in Tilapia aurea, Tilapia galileae and Auchenoglanius occidentalis and lower than those reported by Anene (2005) in four cichlid

The 'littoral' cichlid
is yellow and prefers shallower water, while the "benthic' cichlid
is blue and prefers a deeper habitat.

In September 2007 and May 2014, the Asian fish tapeworm, Bothriocephalus acheilognathi Yamaguti,1934 (Cestoda: Bothriocephalidea), was found in populations of the non-native convict cichlid
(Archocentrus nigrofasciatus) and mosquitofish (Gambusia affinis) collected from the discharge channel of a water treatment plant in Los Angeles County.
With other perciformes, like Tropheus cichlid
lineages, they exhibit distinguishable morphological characteristics with minor variation due a tightly packed community with limited capacity of dispersal  and this phenimenon might be the cause of the minimal variation between male and female of M.
A test of mutual co-operation in displays', the paper by researchers at Queen's University Belfast, reveals surprising findings about what happens when cichlid
fish view their reflections in mirrors.
The Neotropical Midas cichlid
species complex (Amphilophus citrinellus Gunther 1864) has become a model system for investigating the mechanisms of speciation and adaptive radiation.
The Mayan cichlid
(Cichlasoma urophthalmus) and the African jewelfish (Hemichromis letourneuxi) are now among the most abundant species in parts of the Everglades (Faunce and Lorenz, 2000; Loftus et al.
The Mangarahara cichlid
, from Madagascar, is believed to have vanished from the wild as a result of the building of dams which has dried up its habitat on the Mangarahara River.
