That big boy is a Apisto hongsloi who unfortunately isn't the dominant male in the tank so the female hongsloi has shacked with the male Apisto macmasteri which I'm not happy with but am not willing to sacrifice either. They are hard to come by locally only seen them once and I bought them as a pair my first female didn't make it this was the second. (My buddy's male had died so I harassed him for his female but he had mail ordered.)
Apisto hongsloi
Domain male A. macmasteri (I bought it as a viejita which I'm told are easily confused) This is him displaying for the female dull color difference from above. I'm told they can cross but there hasn't been any proof of that.
