Take a look at this Panaque, beautiful markings. Does anybody know which species it is?

Nothing I have seen before. I wonder if this is a regional variation or just an individual fish with a strange pattern?

This fish may be from either Rio Araguaia or Rio Tapajos, or very closely related to either population, I think.
A very similar fish was in a Japanese magazine in 1997, Aqua magazine vol. 34, pp13 (PR015), but the fish was from Rio Araguaia and looks different to the fish asked here.
Because this fish has more concaved under eye part and shorter dorsal spine than usual Rio Araguaia specimen (or at least look like it does to me in these pics), I assume it would be a Rio Tapajos specimen. ...wait a minute. The fish do not have a wide caudal fin. I never seen Rio Tapajos royal with such a small caudal fin before, and it looks like Rio Araguaia fish on that point...
2 possibilities.
1. Long kept Rio Araguaia royal in an aquarium.
Rio Araguaia fish tends to develop chaotic black lines like this fish during a long period of time kept in aquarium condition, usually with non-frequent water changes.
Less frequent water changes in aquarium tank often develop that black line pattern in royal Panaque. Fish stop growing under such a condition but only line pattern changes somehow. Slow recovery from severe skin damages in the past sometimes change the pattern too.
2. Rio Tapajos specimen with a small caudal fin (damaged when young?).
Most likely #2 to me....
