Is this a pair of Apistogramma cf. moae?

The biggest "problem" , or actually the biggest fun is this: I bought these fish at a very reputable LFS. One of the best in the Netherlands. The owner and his staff know their stuff. They sell them as Apistogramma cf. moae. Their information about the fish is: collection site: Rio Yurua Peru.
But if you look at them they have a lot of the characteristics of A. cf. eunotus. Eunotus is a large complex with transitional forms and the characteristics are very diverse even within a population. Sometimes A. moae is placed in the eunotus complex. I just follow Mike Wise's advice. They could be cf. moae or cf. eunotus. If the collection site truelly is Rio Yurua Peru, cf. moae is better fitting. But the fish have a lot of cf. eunotus, I admit. I guess we will never be completly sure.
Perhaps Apistogramma cf. moae aff. eunotus or Apistogramma cf. eunotus aff. moae is an option? (I'm kidding)

Well you might know one day if they colour up and match a known catch.

Is'nt it amazing how different the same fish can appear in different moods? I now am more certain that Frank's identification is correct. It is a form/population of A. cf. eunotus.

Your supplier can be the most reputable one around but no one is totally knowledgeable on every fish. Most, like all of us who don't collect the fish ourselves, have to depend on information that is given to us. Yes, your fish could be from the Rio Jurua and be exported from Cruzeiro do Sul and still not be from that location. The Jurua is a tributary of the Amazon and your fish could be from the lower, not middle, Jurua. There are typical eunotus-subcomplex species from the area. Cruzeiro do Sul could also be where the fish was shipped, just like Manaus is the location where most Rio Negro fish are exported. Neither city is the actual collecting site. This is only a guess. We probably will never know for certain.

Thank you. Like I said, I actually find this fun. I still follow your advice. So from now on I will refer to them as A. cf. eunotus.
