Toyin, do you have more pics of the fish? Or do you wanna see what we think based on the head shape?
my first thought based on this pic alone would be that it's not Pbb, but i could see how it might be, and since this looks to be a young fish, perhaps it hasn't quite developed the characteristic look. But again based on this pic, i would lean more towards a lap or something else. In fact, it reminds me of a guinea lap or one of those guinea lap variants or some other guinea species. But since you asked if it's a Pbb, i'm assuming it wasn't from Guinea??
