Looks like a Hypostomus, but according to Fishbase, there's no Hypostomus species in Orinoco.

Probably still a hypostomus specie... ;-)

Thank you for ID this fish.

Here I have some picture of catfish from central Peru - Piches River.

Pterygoplichthys, Liposarcus, Glyptoperichthys or Hypostomus?

Chaetostoma?

First two pictures: If I'm counting the dorsal rays correctly (seven, maybe eight), I would say Hypostomus.

It is picture from my friend. I do not know the number of dorsal rays and if is it possible to see the whole fin on the picture.
