Doug Brown is correct. It is Apistogramma sp. Rotpunkt. If the lighting is correct and the male is actually this yellow instead of having a bluish cast then it's A. sp. Rotpunkt (Puerto Narino). Your male shows the name sake red spots behind the gill cover on the flanks. Your female looks like a macmasteri-group female but doesn't have the diagnostic ventral patch found on all macmasteri-group females. The Rotpunkt Apisto exhibits features intermediate between the regani-group and the macmasteri-group. It's what I call a "bridge species" between the two groups. These fish have been collected in the Colombian Amazon (Rio Caquetá) and Colombian Orinoco (uppermost Rio Guaviare, I think) along the foot hills of the Andes. This area is intermediate between areas inhabited by regani-group species (eunotus-complex) and the macmasteri-group. All of the various color forms (Rotpunkt (Red-spot/point), Schwarzsaum (Black-edged/fringed/rimmed), Puerto Narino, and Blue-cheek) are white water species that readily breed even in slightly alkaline, moderately hard water. Males are highly polygamous and "sneeker males" are common. I even had a male take on the female's brood colors and pattern and join the female in guarding fry. I thought it was two females tending the fry, but they never succeeded in raising any of them. That's when I realized that I had a male in females clothing. The Rotpunkt apisto is very common in the hobby and makes an excellent beginners fish. Mike Wise plasticolor@guate.net wrote: > Hi everyone: > > I`m looking for some help to identify this species.
