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). Research is required to evaluate effects before conclusions can be made.

Cichlasoma dimerus has typically three anal spines, unlike the otherwise similar C. bimaculatum (Black Acara) which has typically four anal spines (Kullander 1983). In the spleen, FLX caused an increase in the area and a decrease in the number of MMCs. These differences may reflect seasonal use, habitat availability, interspecific competition, or predator avoidance and support the generalist tendencies of this species. Novakowski, G.C., F.A.S.
