A Halfmoon ("HM"), as it's name refers to, requires a betta's caudal to form a nice 'D' shape (180 degree spread), so those that don't reach a 'D' are at best Superdeltas or SDs. To be even more exact, the outermost caudal edge must also be as long as the caudal fin, so as to form a 'D', otherwise the caudal has a rounded edge. Think of a protracter that you might have used in school.

This is the most basic criteria for a long-tail betta to be called a HM. But to be considered a good Halfmoon, there's more to it than just the caudal. But that's another story for the future.

What about HMPKs? For this, there are two main schools of thought. The first school of thought takes the same definition from long-tail bettas, that a 'D' caudal (180 degrees spread) is required. The second school of thought is that anything with 4-rays and above would be considered, whether or not the 'D' caudal is achieved. I leave it to your own choice on which school of thought you would like to follow.

Hope this helps our new friends on this forum. When they see a fish called "HM", they would at least think hard whether it qualifies. Not every fish called a HM, is one. And for very obvious reasons.

All the best in your betta hobby.
but if the parent both are HM and the out come if haven reach a HM we call it SDs?are you trying to say that 804 HM are SDs?==> http://www.arofanatics.com/forums/sh...d.php?t=329466 ? mind explain?
