Table 1. Courtenay, W.R., Jr., H.F. Sahlman, W.W. Miley II, and D.J. portalegrensis may refer to C. dimerus, C. portalegrensis, or C. bimaculatum; records from before Kullander’s revision of Cichlasoma in 1983 should therefore be treated accordingly. Cichlasoma dimerus has typically three anal spines, unlike the otherwise similar C. bimaculatum (Black Acara) which has typically four anal spines (Kullander 1983). Hence, C. dimerus males showed important changes in its hormonal profiles and testicular cellular composition throughout the reproductive and parental care period.

Brazil country information . The male parental care period was divided in four different phases according to the developmental degree of the offspring: pre-spawning activity (MP, day 0), guarding eggs (ME, one day after fertilization (1 DAF)), guarding hatched larvae (MHL, 3 DAF), and guarding swimming larvae (MSL, 8 DAF).

Although C. dimerus can tolerate temperatures ranging from 6°C to 30°C (Staeck and Linke 1995), optimal breeding temperature is around 25-27°C (Meijide and Guerrero 2000, Meijide et al. 2011, Meijide and Guerrero 2000, Meijide et al. and L.
