jsodwi;495066; said:The melafix should not have hurt the fish maybe the fish was too far gone. Its all natural so unless you used the wrong dosage I doubt is was the Melafix

Melafix is based on melaleuca tea tree extract as an active ingrediant.The active ingredients in tea tree oil have a similar structure and action as turpentine.
