The fish are still young. It is almost impossible, based on the available photos. I have a "gut feeling" that it is a form from the lower Amazon (below the Rio Madeira), but I cannot say which it is.

Still young looking (rounded tail on male), but the pattern of dark markings on the body point to a form found in northern tributaries of the lower Amazon between Manaus & Óbidos. Koslowski called it A. agassizii Netz/Net form. If it is this form, then the males get large, massive body with long streamer-like tips on the dorsal & anal fins. The caudal fin can get a long tip, too.

It looks like the Net form of A. agassizii to me. You can't put an exact name on the fish unless you know for certain where they were collected.
