Does anybody know is this one?

Hello, I need help, my wife bought some catfish and she doesn`t know them surely.
Is this a S. nigrita?







Pleas answer soon if possible
Thank you

It does look like one, yes. It can be difficult to tell nigrita from

Synodontis robbiana

, which is a smaller species.

@Chrisyhthys
Thank you for the first information, but my catfish are between, the smaller one 17 cm the greater one is about 22 cm.
I think this is too much for S. robbiana.
In fact of this, I think it`s S. nigrita or posssibly S.eupterus

Please send me more opinions

If they were euptera (the new name for eupterus) they would have the feathered dorsal fin by now. I think they are most likely nigrita.

Unlikely that it's

Synodontis euptera

, body shape for large fish is wrong, as is the dorsal fin.
