I'm curious what characteristics are making people think this is a Duopalatinus and not a Brachyplatystoma...B. vaillantii is a very common species throughout the Amazon, so it seems that it would be likely to turn up in the hobby.
Catfish Id needed please
- Thread starter herman moorr
- Start date
IME 99% of the fish marketed as vaillantii end up being a
- Pimelodus albicans
- Iheringichthys species
- Propimelodus species
- Duopalatinus species.
These may help further (and the links therein too):

Thanks Viktor...
I guess it would make sense that a lot of these smaller silvery pimelodids get exported as juvie vaillantii.
That being said, I'm strongly doubting Duopalatinus on this one. My understanding is that for that genus, the pectoral spine is short...about half the length of the next soft fin rays. I don't see that in any of the pictures, but perhaps they're not clear enough.

To me off all the proposed this species look a likes...this one is best fit ime. Also brachyplatystoma have small eyes and large mouth. This fishes mouth is bigger than the typical pim but is not like a brachyplatystoma. Eyes are too big for head as well. The fish I would say is true vailantii has body of brachyplatystoma capatretum just gray to brown in color. Either way I will keep this one just to see how he turns out.
I trust your info. In reply, I'd say that pectoral spine length is hard to gauge in side shots. The fish profiles, body and fin proportions observed in side shots appear close between the Duopalatino and the vaillantii. Or maybe I trust PCF experts too much. Sorry, no time right now to take a close and long look. Just going off memory.
EDIT: Oh sorry, you are talking about this OP fish, that particular one. I took it as a general statement. My bad. Disregard.
