Knowing that your fish are from Peru and show distinct split bars, it in fact doesn't makes any sense at all to call them A. cf. moae instead of A. cf. eunotus.
One of your fish shows very distinct split vertical bars, something I have never seen on any A. moae. On all the pictures of the latter I know, merely in one picture I can see a very faint split bar. Therefore, unlike A. moae, your fish are for sure an eunotus-subcomplex species and if this is...
#2 is A. sp. Blutkehl. Depending on the shape of the caudal fin #3 can be A. iniridae (rounded caudal) or A. sp. Blutkehl (two tipped/lyrate caudal). #1 & #4 can also be A. sp. Blutkehl or some other uaupesi-like species. Have they all been collected together or at different locations, if so where?
My guess would be A. sp. Blutkehl but I'm not 100% sure from these pictures. Please show some more pictures of male and female when not displaying. The black markings on the abdomen are the crucial feature here.
I personally would not breed with specimens from different locations, since recent research suggests that different location usually means genetically different species. Because of this, most tank bred strains of "superspecies" like A. cacatuoides, A. agassizii, A. bitaeniata etc. are almost...
I've heard that there have been cases where exporters have allegedly put females of "similar" species together into the same tank and then sent them out randomly with males of the two species. In this way the wild caught parents of these fish might already have been two different species. Imo...
If they were A. feconat I would expect a larger caudal spot (male and female) and a larger lateral spot (female). Moreover, on all pictures of feconat I know the males show at least some (often many) dark scales in front of the caudal spot, particularly below the lateral band.
If they are hybrids I would refrain from breeding them at all.
I can't tell you a number. It's just that I personally have no idea which other nijsseni-group species it could be and together with the deformed scales of the male, for me, hybridisation is a likely explanation.
