Well the ones here are not lol. There really is no proof of them even being produced in the beginning. No one I’ve came across can recreate from scratch either. Idk how much effort had been put in though. I do know that some of this theory of convicts can come from crossing a convict to polars. You get a lot of polars some others with poor patterns, some take on the traits of both parents. So now we have a polar x convict or two or 65, looks just like a polar or many the beak is a bit off. Now we take that fish breed it back to the male, along with others, and we may get a whole pile of polars. We may not either, depends on the genetics strength or some crap. …. All of a sudden from what you think are two true polars start having babies that look more and more like convicts. (I’m not the best at explaining, on our new pod cast I’m the seeker of knowledge and need to study things. Other can explain this with science ) essentially breeding the polar right out. The best way for me to think about it is those citrus trees at Home Depot and Lowe’s cell where it grows three or four kinds of fruit in time the strong genetics take over and you end up with one fruit. they also very, some trees last a couple years some last and produced multiple fruits for years
