It was next to impossible to get a good picture of him with my fangled lights, but you can see how his face isn't jet black like some PBTs, the black on his tail is really washed out, and he's got practically no white framing his face. In fact it might not be that his face is any less black, it might just be the absence of bright white around it that makes it look that way.
Say compared to this photo I stole off the internet, which is what all the PBTs I saw in Ocean Creation recently looked like. I'm also now just noticing that my guy's fins on the bottom part of his body are the same colours as the fins on the top, whereas in other PBTs they're snow white.
Are those things that can change, or even affected by diet?
ETA: you can see my very preggers daddy Bangai cardinal in the background of the first pic!
