I don't see how in the video it shows it being uncomfortable and unhealthy for the fish?
Mind you I am not trying to get people riled up and angry, but I honestly think the large pectorals look good on certain fish. It's a different look from the standard betta, so yes I can see in that sense it would look weird.
I have been looking at the threads people post about bettas they want, and I usually look at fish on aquabid that people have a bid on, to try to figure out why people are bidding on them. (Assuming most people who buy off aquabid would be doing so to better their breeding stock. I know in many cases this is not the case however.)
I know big ear fish aren't show quality material but I don't think it looks like a harmful trait? I value everyone's input, considering this trait intrigues me.
I also don't really want to be labeled as a monster because I think it's pretty. As long as it is moderated so people don't go insane going for "Who has the fish with the biggest pectoral fins." In a case like that, yes I think it is sad, picturing a fish who can't swim or stop, and sinks because their fins are too heavy for them.
As for the fin chewing, I have no experience in that personally, I read something that tail biting was passed down genetically. I was not aware bettas chewed off their fins to dump extra weight. (I am still really new to bettas) I thought blowing their fins meant they ripped off, like a dog blowing its coat, or a bird molting?
