He had a battle with ich a few weeks ago, but has been getting better. Before he was covered in white spots, but it has all but cleared up now (3 spots are all that I can see left). He's been eating very well, but what concerns me are these 3 bumps on his side. Any ideas as to what it may be, or how to treat it? I've been adding formalin to his holding tank for about 5 days now in order to help kick the last of the ich. Thanks for the help folks
