And if it really is and mated with my Nsukka females, will their offsprings be considered as a hybrid?

Early experiments by Col. Scheel and others proved that truly different species could produce viable offspring, but usually with poor fertility. Also some fish that looked identical and were identified as a single species, did not even have the same number of chromosomes, hence could only produce infertile "mules." They were from two different locations.
Fp. gardneri (GAR) from different collection locations have thus been kept pure, and genes not mixed. One former GAR is now known to be a different species, entirely (Fp. nigerianus). If you cross GAR from different collection locations, they may be perfectly viable and do no harm. Just keep the offspring as "aquarium strain" and never, ever, use one of the original locations to identify them after that. They may carry subtle tendencies to infertility, so we don't want to lose our N'sukkas and Akures, like we did some lovely species in the '70s.
