“…LoVullo et al (1992) provided observations of parental male catfish (Bagrus meriodionalis) exposing their broods to invertebrates by spitting the food into the nest. Other likely examples could be the many cases of trophic provisioning in catfish and cichlids (Noakes 1979). Also in coral reefs, some juvenile fish swim with (unrelated) conspecifics after recruitment from their pelagic stage and could therefore also learn what and where to eat by observing conspecifics.…”

We provide selected examples from the fish literature of phenomena found in fish that are currently being examined in discussions of cognitive abilities and evolution of neocortex size in primates. In the context of social intelligence, we looked at living in individualised groups and corresponding social strategies, social learning and tradition, and co-operative hunting. Regarding environmental intelligence, we searched for examples concerning special foraging skills, tool use, cognitive maps, memory, anti-predator behaviour, and the manipulation of the environment. Most phenomena of interest for primatologists are found in fish as well. We therefore conclude that more detailed studies on decision rules and mechanisms are necessary to test for differences between the cognitive abilities of primates and other taxa. Cognitive research can benefit from future fish studies in three ways: first, as fish are highly variable in their ecology, they can be used to determine the specific ecological factors that select for the evolution of specific cognitive abilities. Second, for the same reason they can be used to investigate the link between cognitive abilities and the enlargement of specific brain areas. Third, decision rules used by fish could be used as 'null-hypotheses' for primatologists looking at how monkeys might make their decisions. Finally, we propose a variety of fish species that we think are most promising as study objects.

“…According to Chong et al (2005) amino acids and essential substances in the mucus are extremely important in the early days of larval development. This same behavior is also known in neotropical species of S. discus, midas cichlid Cichlasoma citrinellum (Günther, 1824) and in two species from Madagascar and India; orange chromide Etroplus maculatus (Bloch, 1795) and pearlspot E. suratensis (Bloch, 1790) lineage (Hildemann 1959;Noakes 1979;Noakes and Barlow 1973;Ward and Wyman 1977). According to Buckley et al (2010), males are generally darker than females and therefore the larvae feed more with the former (Buckley et al 2010).…”

Description of the reproductive behavior of Symphysodon aequifasciatus (Cichlidae) in captivity

et al. 2016

The blue discus (Symphysodon aequifasciatus) is often sold for ornamental purposes. It is a neotropical cichlid from South America, which is native to the rivers of the Amazon basin of Brazil, Peru and Colombia. The purpose of this study was to characterize the reproductive behavior of S. aequifasciatus and identify features that can later be used by breeders to facilitate the handling and reproduction of this species in captivity. The experiment was divided into two stages: the first dealt with partner selection and couple formation to observe the behaviors of territoriality, pursuing, fleeing, biting, stay, protecting and cleaning of the substrate. The second stage documented mating behavior, nesting and parental care, to observe vibration, spawning, permanence with the offspring, aeration of eggs, cleaning of spawning, color change and shift-taking in parental care. The results of the study allowed identifying disputes for and establishment of territory, as well as the selection and cleaning of the substrate for spawning performed by both sexes. The parental care was observed from spawning in the substrate until the care for the larvae. It was found that the reproductive success of this species is closely linked to biparental care observed during the entire reproductive process and early stages of the hatchings. KEYWORDS: Amazonian Fish, Ornamental Fish, Larviculture, Reproduction, Behavior Descrição do comportamento reprodutivo de Symphysodon equifasciatus (Cichlidae) em cativeiro RESUMO Dentre as espécies de ciclídeos neotropicais comercializados para ornamentação, destaca-se o acará-disco (Symphysodon aequifasciatus), que é um ciclídeo neotropical originário da América do Sul, pertencente aos rios da bacia Amazônica do Brasil, Peru e Colômbia. Este estudo caracteriza o comportamento reprodutivo do acará disco (S. aequifasciatus) identificando características que posteriormente possam ser identificadas por criadores e utilizadas para facilitar o manejo e reprodução desta espécie em cativeiro. O experimento foi dividido em duas etapas, a primeira com a escolha de parceiro e formação do casal, e a segunda com acasalamento, desova e cuidado parental. Na primeira etapa foram observados os comportamentos de territorialidade, perseguição, fuga, mordida, permanência, proteção e limpeza do substrato, enquanto que na segunda etapa os comportamentos observados nesta etapa foram: tremor, desova, permanência com a prole, aeração dos ovos, limpeza da desova, mudança de coloração e revezamento do cuidado parental. Como resultado foi possível constatar disputa e estabelecimento de território, bem como a seleção e limpeza do substrato para a desova realizada por ambos os sexos. O cuidado parental foi observado desde a desova no substrato até o cuidado com as larvas e o sucesso reprodutivo desta espécie está intimamente ligado ao cuidado biparental observado por durante todo o processo reprodutivo e estágio inicial dos filhotes.

“…is also widespread -at least 28 species have been reported to exhibit fry mucus-feeding behaviour in four families (Noakes, 1979), and this behaviour has evolved many times, in species separated on distant branches of the fish phylogeny, including the Osteoglossiforme Arapaima gigas (Liiling, 1964;Menezes, 1951).…”

“…are feeding on the mucus secreted by their parents (Chong et al, 2005;Noakes, 1979;Perrone and Zaret, 1979) [see also Hildemann (Hildemann, 1959) and references therein], it has also been shown that, in contrast to mammals, mucus is not the only meal they are getting. Critically, Bremer and Walter (Bremer and Walter, 1986) found that there are more secretocytes undergoing mitosis in breeding individuals of S. discus than in non-breeders and analysis of the faeces of the contacting fry showed that they were consuming these cells and other micro-organisms that are present on the skin of the adults.…”
