Either way, it's a good looking fish.
If it starts to develop some stronger yellows, I guess you'll have a confirmation that it's indeed a bujurquina. I've never seen one before, so my judgements were based on the videos/pictures I had seen, as well as based off my experience with the odds morphs with my BA's.

I bet its tail will have developed a bit more color to it as well. It looks like it's already got a tint of color to it.
