My Jardini Arowana is a happy 13 inches and had a little slit in its top-back fin and the tail-fin. both have progressively gotten larger and more noticable over the last couple months. No signs of blood vessels around the injury/disease, although i have been using some aquarium salt and have been keeping up with water changes about every 10 days (with about twice as much flitration necessary). SO...how may i get rid of this?
