I would say so. We need JL to explain lol, he has both in dark tanks, his Venezuelan are dark but his amapa next to it shows the difference, on his Venezuelan you can still see slight difference in color where the bars are where as amapa looks pitch black.My aimara has been pitch black since I got it at 13", now approaching 16-17" and still black as ever. Always in a pissed off mood. I never got a confirmation as to which catch point it was. Perhaps it's an amapa?

That is interesting. I never knew of this. Wonder why that is..My Amapa didn't turn black till around 10-12".... My VZ and Amapas looked the same as juvies......
Reason it was black could have been mood - Never did try keeping it alone.
From November 2016 your aimara has only gotten to 14in? What size was he when you got him?
He was in a 2 footer tank all the time, only intro him into main tank(containing huge bichir) a few months ago.From November 2016 your aimara has only gotten to 14in? What size was he when you got him?
Mine is 15in and has grown 11in in the 15 months I’ve had him (since March 2017).
