These are wild caught we brought back from Peru. I don't have a reliable collection site. What are your thoughts? Hope these links work.

Looks just like the A. cruzi I just brought in from Peru.

Like Jeff wrote, it probably is the same fish usually imported as "A. cruzi", but it isn't the true (holotype) A. cruzi. It is a eunotus-complex species, probably in the cruzi-subcomplex. I really can't say which form without seeing photos with more diagnostic features. It might be A. sp. Nanay/Melgar; the caudal spot is a bit odd (roundish instead of squarish). Another possibility is A. sp. aff. cruzi (Picuruyacu).
