Very nice to see some pictures of what you are up to.
is listed as
Ucayali, which is quite some distance, in most reasonable definitions of "distance", from Rio
Branco, unless you are talking of a different one than the one branching to the north then east from the Rio
Negro that joins the
Amazon at Manaus...
Not convinced on the
P. gibbiceps either - looks more "spotted" than I'd expect them to be.

Yes, it is a large distance, but that's not to say they aren't found all along the way. Alternatively, it may not be
S. nigrirostrum; was just a guess based on superficial similarity. It had a black snout.

Bear in mind these were very big ones, and do tend to look different from smaller ones in the trade. I think
P. gibbiceps is a complex of species, also.

I got several P gibbiceps, bought all in once, 9 years back. 2 of them are in my biggest tank, both are ~40 cm, where 1 is much more spotted than the other.
I can't say whether P gibbiceps is e complex or not, but I think the individual difference can be high too

Thats my guess too, I caught a similar one in Bolivia, and it's for sure not a
Calophysus macropterus.

I had considered that, but fisherman assured me it was
. Perhaps they don't distinguish them?
I checked the higher resolution photos, and the barbels are flat, which would make it
?
