Help with ID of Syno - is it a hybrid?

Hi everyone,
I have 3 of these, have had them for about 3 years. They were labelled as S. decorus when they were bought as tiny juveniles - pretty obvious that's not what they are! The pics are of the largest dominant one, the others are about the same but with a few more dots (they are too shy to come out for a good photo). The closest I can find is S. ocellifer, but what bothers me is that the adipose fin seems not big enough. Of all the Syno's I have seen here in Australia for sale it seems that we tend to get pure species, I have never seen any obvious hybrids around for sale. But I wonder if these ones I have are? Any help will be appreciated.

Thanks,

Collingwood

Synodontis ansorgii comes to mind. How big and frequent are the spots on the other two?

Hi,
thanks very much for the quick reply. I have found a pic of one of the others (though both of the others look the same, only the one I posted first has less spots). Hope you can excuse the grotty glass!

Synodontis ocellifer x Synodontis eupterus hybrid - my guess.

Could be S.velifer, large wide humeral process looks about right.

Synodontis velifer has a larger adipose fin (almost as large as in S. eupterus) and would have much longer first dorsal-fin rays.
