From planet catfish.......
"Similar to four other described catfish from the lake. The cuckoo catfish, Synodontis multipunctatus, is the most common import and you, occasionally, may also encounter S. polli, S. dhonti and S. tanganyicae. All sport the distinctive white barbels and are spotted as juveniles to some degree or other and thus another form of quick identification prevails - S. petricola and S. lucipinnis, are the only species with a solid white leading dorsal and pectoral fin ray and the spotted body pattern. S. petricola can be differentiated from S. lucipinnis by the former having smaller spots on the head than the body spots.
All in all. this species (as presently defined) is highly variable and likely to contain more than one valid species in the long run."
So it isn't S.petricola or S.lucipinnis
