The Half Moon (or Halfmoon, or HM) is the hottest tail form going today, and with good reason. These guys look great even when not flaring, and when the do flare the effect is astounding; a huge tail that spreads straight up and straight down, full dorsal, and symmetrical anal fin. They are quite an accomplishment in betta form.
Specifically, a halfmoon betta must have a caudal where both ends are exactly 180 degrees apart or more, spreading towards the front. Caudal edges have to be straight or curving outwards, and not bending inwards.
There are a few important things to strive for when breeding for a Halfmoon betta:
1.) Symmetry - the body line that cuts and seperates the caudal into half.
2.) Balance - the ability to draw an arc that begins from the caudal and encompasses the dorsal and anal without hitting a snag.
3.) 180 degree caudal with straight and crisp edges.
Few people disagree with the above statements. The only area of disagreement, or rather a difference in opinion exists in the 'proportion',i.e. the caudal/body ratio.
When caudal/body is less than 1, you get an 'oval shape'(OS). But when caudal=body or caudal/body is 1, you have a 'circle'(CS). The OS Halfmoons are good, but the CS Halfmoons are truly exceptional, and an excellent model to aspire to.
