Ohm is a betta with a tail over 180 degrees. Of course, it is also a HM, and it is the best in HM.
The performance of CT is that there is a needle at the tail, like the crown worn by the king (Europe), called the crown tail, and some of it looks like the mane on the lion's face, so the Hong Kong area is called the lion king fighting fish, which is my favorite one.
The English abbreviation PK for general fighting is actually short-tailed fighting fish, with a short tail but strong body. Among them, the strong one was selected by people for "intensive training" and developed in the direction of fighting, but his colorful and beautiful swimming posture also attracted many players.
