Different morphs and locality of A.elizabethae

[valice]

Is there a physical difference in the three morphs of A.elizabethae?

I noticed that the one from Rio Uapes have a slightly deeper body compared to the ones I see from Tucano. Also, those from Tucano seems to have a "longer" face than those from Uapes.

Using medeiros' picture which he posted in the past:

Using my picture of one from Uapes

What do you guys think?
Issit just my own illusion? But looking at live specimens in the LFS, Tucano ones seemed to have longer faces.

Actually Tucano is merely a town on the Rio Uaupés. I think that you are looking at fish of different ages and some are new imports and not as well fed as others. I can only separate the Rio Içana form from the Rio Uaupés form. The Içana forms have more metallic blue on the face. Otherwise they show identical markings.

I had the blue form back in the 90's. I haven't seen them since.
