Genetics can go further than visual, and this is referring to wild fish not captive bred line strains.

we don't even know where exactly polypterus fit in the evolutionary chain, they could be ray finned or lobe finned or somewhere on their own (even through genetic tests on ornates).
Without scientific testing how can you say it's definitely not? It's certainly different to the wild caught fish

posted, they still look similar to those in the trade today in terms of Colour and tail shape too. I have suspicions, I must speak to the professor about genetic testing...
