made by Aqua Soma Labs. It is used when bacterial problems appear, such as fin and tail rot, columnaris (often seen as cotton wool disease), bacterial hemorrhagic septicemia, and other internal bacterial infections in freshwater and saltwater aquariums. It is also chosen for racing pigeons and other pet birds during respiratory infections, mycoplasmosis (mycoplasma), or suspected chlamydiosis (also known as parrot fever, psittacosis, or ornithosis).\u003c\/p\u003e\n\n    \u003cp\u003eIf you used to buy the discontinued Thomas Labs Fish Doxy, Aqua Doxy, or older Bird Biotic, Fix Doxy is the online replacement.
