Stan, those CANNOT be from Peru lah.

I'm 99% sure the pic is of adult real altums. I've got a few sitting in display tank in Aust.

Peru does not export the REAL altum. Altums only come exported from South America thru Columbia and infrequently thru Venezuala. Anytime u see Altum on a Peruvian list it won't be the real thing.

There is a similar high finned wild angel out of Peru which some of the Germans have called P.scalare peruensis aka Peruvian altum. These look like the shape of the real altum as juveniles (except the bars are thinner), but never grow to the size of the real altums.

Eh, btw as far as I know there's no official "grade" system for altums. They come as they are caught. Any "grade" is superficially man made.
