I keep both mentioned and rio niltepic as well. My pairs go in this order with aggression: niltepec, sarabia then naranjo.
Sarabia have my favorite color but shape more important to me so I prefer naranjo and found that the niltepiec have attributes of both
Rio sarabia most prolific, niltepec second with naranjo last. Naranjo hardest on female, sarabia second and niltepec not
Some of the baby niltepec I got don't grow but the ones that do grew faster than sarabia and naranjo
Niltepec and naranjo live in separate community tanks but sarabia can't
My current favorite are a female naranjo and a male niltepec (obviously they not together as pure blood is important to me) at some point I'll need thin out and first on chopping block would be niltepec and the only certain 'keeper' is male from rapps back in the day. I can't determine collection point, may not be pure blood. He paired up with female lyonsi accidentally. Obviously I don't sell fry as hate the fact today it's nearly impossible to find true texas or Midas or trimac etc because of all hybriding....but my limited knowledge without any scientific backing I believe this pair more of cross breed rather than hybrid. I think at one time they were the same fish that evolved differently due to environment like so many of the amphs but most of us have opinions and they could all be wrong.
In conclusion anger management cichlids has the best sarabia. COTA recently had nice naranjo. Max cichlids sells niltepec for cheap and has great customer service.
Everything above is based on my personal past and current experience but everyone's experience is different and so many factors involved including but not limited to: water quality, temperature, space, tank mates, did pair grow up together, food type/frequency, aquarium location, pond vs aquarium, size differential between male and female, individual specimen personality, does tank next to them have giant RTM pair or harmless grow outs, etc...hope you enjoyed reading as much as I enjoyed typing
