Basic ID

Belongs to the elegans-group so has a wedge shaped head.


Looking at the fish from above, the female is widest at the center of the body, while the male is widest just behind the pectoral fins.
When they are well fed or in breeding condition the female is always plumper, also seen from the side.

Males are normally smaller and have longer pectoral fins with a dark blotch at the top. Their pelvic (ventral) fins are more pointed.
Females are normally larger, duller colored and less contrasting, and have rounded pectoral fin. Their pelvic (ventral) fins are rounded to form a pouch for the eggs when spawning.
