Hmmmmm.....
WAITAMINIT, here.
For one, the African Cichlids you purchased were priced substantially cheaper than the 'pure' species you could have sourced out and purchased from an online vendor. Whew....you add the cost of shipping onto that online purchase, and you're into a pretty substantial investment.
For another, those Cichlids look pretty decent to my eyes, at least. I mean, when you looked at them in the tank they were offered for sale with - they didn't look like hot garbage or something did they? NO!!! They looked colorful, pretty and seemed like they would make nice additions to your aquarium.
And lastly, be true to your own intent. I mean is the point to get 'pure' species African Cichlids of a proven provenance, so you can sell the babies or something later? Trust me on this, it's doubtful at the scale you will bring with a home aquarium, that you will clear enough cash in the sale of those babies to even cover the annual costs of providing electricity and food for that tank! No one (not even the 'BIG GUYS' makes the so-called 'Big Bucks', selling tank-raised African Cichlids).
Do these colorful, healthy fish make you happy? Great! Enjoy 'em! And no.... I would NOT distribute any of the babies produced by that tank to anyone. But, that may not be the point of this aquarium, right? So, just enjoy the colorful and happy Cichlids you have now, in the nice-looking aquarium you've set up for them to live in. Seems simple enough to me.
