I to had no idea, Eliott. These are amazing. I had the same surprise after not paying attention to the discus hobby for 25 years. I left with only visions of wild discus dancing in my head only to return to what we now have. Now betta fish. Do these hybrid males still fight if you put 2 of them together? If so I can imagine the fin carnage. And today I was horrified to learn there is something called a "bulldog" discus? Sorry but that is one buh tuggly fish, in my opinion. Why do that to a fish? These betta on the other hand are very nice.
