i've read in thailand fighting fish website,he using banana leaf to recover back,or heal the injured fighter fish (plakat) or to make the scale of the fish tougher. Using the dry one, soak it in the water like u using the ketapang leaves method. i think its good for the plakat thou but if using for the Hm,the water might burn out the soft fins of the fish. coz,i've been using banana leaf before.
