Yes, those are onyx, very nice looking ones as well. Onyx are merely a color variant of true perculas, which have a wide range of color intensity and patterning. It is not uncommon to see a lot of natural pattern variants coming out of the Solomon Islands, and natural color variants (especially heavy black overtones) in fish from Papua New Guinea.
