Coloration

Overall body color varies from olive-green to brownish-grey, often with a yellowish or reddish tinge on the belly and lower flanks. The most distinctive feature is the bright red or orange coloration on the operculum (gill cover) and sometimes extending onto the chest and throat, especially in breeding males. Juveniles and non-breeding adults may have 6-9 faint vertical bars on their flanks. Fins are typically dusky, sometimes with reddish margins.

Identification Tips

1. 1

   Opercular Spot

   Look for the prominent red or orange patch on the gill cover, which is the most reliable distinguishing feature.

2. 2

   Body Shape

   Observe the relatively deep and compressed body, typical of many cichlids.

3. 3

   Fin Spines

   Count the anal fin spines (usually 3-5) and dorsal fin spines (14-17) if possible, as these counts can help differentiate from other tilapia species.

4. 4

   Mouth and Teeth

   The mouth is relatively small and terminal. Examination of the lower pharyngeal bone (requires dissection) shows slender teeth, indicative of its herbivorous diet.
