In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral approach, including morphological and physiological features. There are several dark-brown vertical bars and two blotches (one in the middle of the body and one on the caudal peduncle). The female laid adherent eggs over the spawning surface in a line of around 10 eggs and then the male passed over fertilizing them and L. Casatti. Scales of C. dimerus have thick gray to black margins on the posterior edge, especially on the head, nape, and anterior-upper flanks, while margins on C. bimaculatum scales were absent to light, and narrow (Robins et al. 1.
