More than likely swim

bladder disease. Its when fish swim up to the top of the tank and get air in their swim bladder...this can make them very sick, and there is no medical treatment for it, all you can do is feed it sinking food for around a week such as sinking pellets or cooked peas will also sink to the gravel. Also if you are using flakes or non-sinking pellets, just soak them in tank water for a couple of minutes then pour the water back in...this will help it sink and reduce the air in the food. Eventually your fish will lose the air if it is fed by sinking food. If not, it will more than likely die. ...
