Just curious as to whether there are any reliable pics of Synodontis Koensis or S.Centralis :?: i know of the pics in D.Sands book 2 , that black and whitish fish , looks amazing, assumedly that would be before the hybrid invasion :?: i've noticed there are three pics of S.Centralis over on Scotcat , though in fairness those pics look to me like S.Waterloti ! beautifully coloured though it has to be said , just curious as to what other people think .

I am sure you have looked in the CateLog, I wont get a chance to look this over until later but I will see what I can find out

All three species are also in Revision Des Africains

Cross referencing all pictures I found back to these(drawings but good ones)makes it seem like every thing is in order in my opinion
i know of the pics in D.Sands book 2 , that black and whitish fish ,
Can't say anything on this fish as I do not have it

Most noticable differences I have found

koensis-deeper body-short stubby humeral process when compared to the others(not all koensis pictures found show the same humeral)-adipose fin slightly taller than centralis but at the very back hooks under

waterloti-triangular humeral process-adipose fin slightly taller than centralis but at the very back hooks under as above

centralis-long pointy humeral process-low adipose fin which does not hook back
i've noticed there are three pics of S.Centralis over on Scotcat , though in fairness those pics look to me like S.Waterloti !
All pictures I found seem to relate to the differences mentioned above quite well...If you compare the picture of the centralis on Scotcat to waterloti or koensis you can see the difference at the very back end of the adipose fin

Hope I make some sense...wish I could explain better

The pictures in Sands CotW vol 2 are certainly pre-hybrid invasion into the hobby. The koensis photo opposite the centralis is indicated as not typical.
