Telling Males from Females. Telling males from females is one of the most common problems a beginning cichlid hobbyist faces. For some species, males and females are readily distinguishable by color, size or shape.
The pearl cichlid Geophagus brasiliensis is a species of fish in the cichlid family. It is native to southeastern Brazil north to BahiaParaguayUruguay and far northeastern Argentina,  where it is found in rivers, lakes, and nearby slightly brackish lagoons. The pearl cichlid has one dark spot which may visible on its body, located towards its tail; it also may display several black bands running top to bottom down its body.
Red zebra cichlids are mouth-brooding mbuna cichlids. Females incubate the eggs and carry their young around in their mouths. In order to breed these fish and witness this behavior, ensure you have a male and a female. You can differentiate between full-size males and females by their size.
Figure 1. While these cichlids may appear to be kissing, do not be fooled. Much like humans, this male and female pair are actually having a small spat and are solving their differences through mouth fighting, a common demonstration of aggression in cichlids.
Metrics details. The East African riverine cichlid species Astatotilapia burtoni serves as an important laboratory model for sexually dimorphic physiology and behavior, and also serves as an outgroup species for the explosive adaptive radiations of cichlid species in Lake Malawi and Lake Victoria. An astounding diversity of genetic sex determination systems have been revealed within the adaptive radiation of East African cichlids thus far, including polygenic sex determination systems involving the epistatic interaction of multiple, independently segregating sex determination alleles.
All other datasets supporting the conclusions of this article are included within the article and its Additional files 1234567 and 8. Sex chromosomes change more frequently in fish than in mammals or birds. However, certain chromosomes or genes are repeatedly used as sex determinants in different members of the teleostean lineage.
The convict cichlid Amatitlania nigrofasciata is a fish species from the family Cichlidaenative to Central America also known as the zebra cichlid. The convict cichlid displays significant color across its range. The type species, A.
I will explain how to do this in this article but only as a last resort, when you absolutely have to know for sure. In most african cichlids, the males will grow larger than the female cichlids. On the contrary, many Tanganyikan cichlids such as the Julidochromis will have a larger female.
