Whats up everyone, new to the site. Here's whats goin on. My oscar and JD have stopped eating. It has been about a week now. The oscar also appears to be breathing very heavily, long,slow breathes. And the JD will suddenly start thrashing around, shaking his head and body violently. My Jag and firemouth are doing just fine. The fish have no visible signs of disease or infection. Any help would be great!!!
