Lateralization of lateral displays in convict cichlids [PDF]

Biology Letters, 2011
We examine lateralization of lateral displays in convict cichlids, Amatitlania nigrofasciata , and show a population level preference for showing the right side. This enables contesting pairs of fish to align in a head-to-tail posture, facilitating other activities.

Cryptobia iubilans in Cichlids

EDIS, 2014
After many years of diagnostics at the University of Florida and at other laboratories around the country, it appears that Cryptobia iubilans is not uncommon among cichlids, and that environmental and other factors determine the extent of disease. This revised 3-page fact sheet was written by Ruth Francis-Floyd and Roy Yanong, and published by the UF ...

Pronounced expression of extracellular matrix proteoglycans regulated by Wnt pathway underlies the parallel evolution of lip hypertrophy in East African cichlids

eLife
Cichlid fishes inhabiting the East African Great Lakes, Victoria, Malawi, and Tanganyika, are textbook examples of parallel evolution, as they have acquired similar traits independently in each of the three lakes during the process of adaptive radiation.

Echoes of Evolution in Holocentridae: Harmony Between Phylogeny, Morphology and Acoustics

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using phylogenetic, morphological, and acoustic data from 53 species, we reconstructed the evolution of acoustic communication in nocturnal reef fishes of the family Holocentridae. Our results reveal two major clades with distinct sound‐producing morphologies and acoustic features, and suggest a three‐step diversification process involving the ...

Food habits of three non-native cichlid fishes in the lowermost Chao Phraya River basin, Thailand

Journal of Freshwater Ecology, 2019
The food habits of three non-native cichlid fishes, Mayan cichlid (Mayaheros urophthalmus), Mozambique tilapia (Oreochromis mossambicus) and Nile tilapia (O. niloticus), in the lowermost Chao Phraya River basin, Thailand, was examined by stomach contents

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, Volume 95, Issue 8, Page 1326-1338, August 2026.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Desert cichlids

Natura
Cichlids were given their name by the French zoologist Charles Lucien Bonaparte (1803-1857), a nephew of Napoleon, who borrowed the term from the Greek κίχλη (kichle), a word that in origin had the broad meaning of “wrasse” (a fish) or “thrush” (a bird).

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

Journal of Animal Ecology, Volume 95, Issue 8, Page 1358-1371, August 2026.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Growth and histomorphological responses of Chindongo socolofi to the long‐term replacement of fish meal with defatted Tenebrio molitor meal

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The long‐term suitability of defatted Tenebrio molitor larvae meal (TM) as a substitute for fish meal (FM) protein was evaluated in Chindongo socolofi over a 170‐day feeding period. Six isonitrogenous (38% crude protein) and isoenergetic (4396 kcal kg−1) diets were formulated, in which TM protein replaced FM protein at 0% (control), 20%, 40 ...

Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia [PDF]

Brazilian Journal of Biology
Cichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation.
