I live in Aus and limited to certain medication. Would epsom salt help? He is eating n swimming but most times..head down...anything i can do to cure his issue?This isn't typical behavior and is a common symptom of a swim bladder disorder. Some fish are more snsative than others. The acclamation is important, slowly balancing temperature, pH, hardness, nitrate levels etc. Try a thirty minute bath in a bucket of tank water with a teaspoon of methylene blue. If it is an SB issue this would help, it won't hurt either way.
