Can the small blisters on the Indonesian tiger, an ornamental fish, be cured?

What kind of blister? Is it suppurating? It's better to take a picture.

My fish had vesicles, which were found to be red early. It should be caused by trauma to the Indonesian fighting frame and poor water quality.

In this case, there is no need to disinfect and sterilize the pus to prevent further infection. Take it out and take a medicinal bath alone. Yellow powder or potassium permanganate can be used. It should be noted that yellow powder needs to be combined with oxygen explosion, and yellow powder Don't overdose on potassium permanganate and potassium permanganate. After it melts and changes color slightly, put it into the medicinal bath.
