Those are all GBR's. No question about it. I've had 3 mating couples over the past 2 years and have seen all shades of GBR's, because they can sometimes lose their color and regain it, in an instant. Their colors will vary based on water temp, pH, spawning habits, and tank mates. GBR's fo' sho' - IMO they are way cooler than Bolivians anyways!
