White butterfly discus or White Pigeon Discus
The white butterfly is the result of the selective breeding of the Pigeon Blood Discus fish. The red checkerboard design has been partially removed to leave only the pearly white base color.
Tony Tan, the Malaysian breeder, invented the White Butterfly strain. Genetically, this strain carries Pigeon genes, hence the facial patterning. The combination of its patterned yellow face and white body makes this a gorgeous and highly desirable strain by collectors.
