Identification Tips

1. 1

   Size and Spotting

   Its small adult size (8-10 cm) and distinct, round black spots on a lighter body are primary identifiers. The spots are generally uniform in size and distribution.

2. 2

   Barbels

   Observe the mandibular barbels; they are distinctly branched or fimbriated, a characteristic feature of S. petricola and some other Synodontis species.

3. 3

   Fin Spines

   Note the presence of strong, serrated spines on the dorsal and pectoral fins. These are common in Synodontis but their robustness can aid identification.
