I bought this at an auction last year. Now I can't remember what it is. Anyone know? It has its own tank because if it is 4 inches or less, it goes in his mouth. Also, is it male or female?
Could be a male Parachromis motaguense.
The two spots on the outer edge of the gill plate, and diagonal tear drop on the back of the eye.
Their coloration, and the exactness varys location to catch location
