Hi, I buy this apisto as Apistogramma Gephyra, but other people say it's agassizii, could help me to identify, which would be the correct name and location of this apistogramma thanks, Greetings

It is difficult to separate the 2 species based on just a few photos, but based on the shape of the caudal, the shape of lateral band in your displaying male, and the prominent darker scale edges below the lateral band I would say that this is a form of A. cf. agassizii (Netz/Net). I could be wrong, of course. Additionally, the female is odd for A. gephyra. I can't recall ever seeing a specimen of female A. gephyra with extensive rows of caudal spots. Are these domestic or wild specimens?

It probably is Netz, but it could be A. gephyra, too. I'd need many more photos of the fish in various moods to be sure. To be absolutely positive I'd need their little bodies preserved in ethanol.o_O
ok Mike, I will upload more photos of them. Greetings

These photos are quite helpful. First, these are not A. gephyra. Second, they are not a single species. The deformation in the rows of scales on the caudal peduncle indicate that these are hybrid fish. We commonly saw this type of deformity in crosses between A. agassizii and A. sp. Tefé in the 1990s/2000s. My guess is that someone was trying to make quick money by selling them as something they are not. Sorry.
