Zusammenfassung:ABSTRACT 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. 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 su
