  1. Buy quality stock , check the water PH level, dont over stock or feed

  2. You wrote a very good post but you don't mention the treatment for each infections.
    Please sir, I need your help.
    I've lost over 1000 fish within a week and I don't know what to do again. I've applied salt, and other medication but the death toll keep rising.

    The fishes had no open wounds, just a well defined pin-point red spot under lateral fin, which was identical in color and size to the one around his anal opening, and a larger but less defined bruise along the side of left fin. belly was swollen and seemed gas-filled. It did not look like trauma to me, that's why I'm worried about a possibly contagious disease (these are common signs in end-stage bacterial sepsis in mammals, but I don't knwo anything about fish diseases).

    Please, can you recommend medication for me. Please, help.
