My bifas came from Rapps & I forget the location point, but it was not chacamax. I don't have pics, but I can describe the differences that I have seen - my fish have a more gold base to them, where the Chacamax has a more bright yellow color to the body. Also the head of my fish is a lighter, more washed out red - deeper red on the chacamax.
Still great looking fish, but I prefer the Chacamax location point. Try to get them if you can.
