What is this auchenipterus?

[aotoo]

from Turiaçu River in Brazil.

Auchenipterus menezesi

is from this area, but we don't have photos of it, and the original description includes only black and white photos of preserved fish, so not very helpful.

That said, the original description of A. menezesi states that this species resembles

Auchenipterus nuchalis

(but A. nuchalis is from a different area, so you don't have A. nuchalis), so you might compare the two.

Good luck!

Thank you. I’m excited to get such a rare fish.

Here's a picture of a paratype of A. menesezi. No use for colouration, but at least it shows a similar fish structurally. Could well be a good ID.
