Well his dorsal fin looks a bit out of line from his caudal. The caudal fin looks to be longer at the top of it and the lower part of it should be more full. The anal fin looks fine to me. The standards say that it can either be a rounded anal or a pointed anal. In his case, he's got a rounded anal. I don't know if it's me, but one of his ventrals look smaller. I think it's how the picture was taken though.
He has very few flaws and IMO great breeding quality. Most of the things are minor flaws.
Quality for giants are the same as regulars. So you want the front ray of his dorsal to be long and leaning forward. And you want the dorsal to be the same height as the caudal. His caudal has unequal ray branching and the webbing IMO is too narrow. You want the caudal to be a half circle - his looks a bit ...just doesn't look right. The edges of his caudal should be pointy - his is too round. You want an anal that leans forward as well. All rays should be firm and straight.
The above is an extreme judgement of show bettas - as you requested, for learning.
That guy is IMO too traditional for my taste. You will have a hard time improving his form. If you plan to breed, look for another guy and get your money's worth.
Fantastic Indjo. Exactly what I am looking for. I look at it like this: I will be paying roughly the same amount for whatever I get. I want great color but don't want to sacrifice conformation to get it. I will keep looking...armed with my new knowledge.
I agree with the person who said the color looks over-saturated. The picture has been edited, you can tell by the blue saturation splotches in the background. I edit photos every single day for my job, I'm trained to look for things like this. xD anyone who feels the need to "enhance" their fish in PhotoShop IMHO is not an honest person, I'd steer clear of the breeder altogether as you don't know what you're really getting.
Rounding of the caudual is acceptable in the traditional hmpk class i believe, the show hmpk is the hard perfect half-circle edge on it. Or at least that's how it was explained to me. That they are two different asymmetrical show classes.
I did find, during my looking around, that the fish was not a bad speciman of the traditional plakat. He would need his anal fin improved upon as well as his branching/webbing in the caudal. I think that would be a tall order for a newbie to find a female to improve those!
