I come from it from a different aspect. I bred and showed show rabbits, cavies (Guinea pigs) and show chickens, and I did show quality Betta Splendens. I also dabbled in show line fancy guppies too. I bred leopard geckos for a bit too. For me, when I get into breeding, it would be for the best quality, representative of the morphs. And being a gambler, I love the gamble of the odds of the outcomes. If fancy rats were more widespread in the US, I’d be breeding to improve my lines and showing them too.
To the person above who mentions GSD, there are more varieties than the “classic” look, black and white. That classic look has a wide variety of actual colors/shades and whether there is an actual saddle, etc. plus there are more colors than just the Black and Tan in what you consider the “classic” look. (I have a black GSD and her littermates included sables and dark agoutis without the classic saddles.)
