Short fins make a faster, more mobile fish that handles normal filter flow and splits its edges far less often than the long tails. Two builds share the name: traditional short tail plakat, and halfmoon plakat, which puts the wide fan on a short tail. They jump well, so a tight lid matters more here than with the trailing forms. Young short finned stock is easy to mis-sex, so shop labels are not always right.
In the wild
Plakat is the Thai word for the fighting fish, from pla kat, biting fish. The short finned build is the traditional Thai form, kept and bred for contests long before ornamental long fins existed. Modern show plakat is newer, putting show finnage and color onto that short tailed shape. It is the closest of the domestic forms to the wild fish, though wild Betta splendens is far plainer.
Good to know
Fin length is inherited separately from color and pattern, so any color offered on a halfmoon can appear on a plakat. Fin length near wild proportions means less drag and less tissue to maintain, so the fish swims harder and takes less fin damage. The body is otherwise the same domestic animal, not a wild import.
Did you know
The name has nothing to do with fins. Pla kat means biting fish in Thai, and it was the label for contest stock. The short finned pet form inherited a word that describes behavior rather than shape.
