Melafix contains Tea Tree extract not Tea Tree Oil. The oil is not miscible with water but Melafix is. So whatever it does contain, it's certainly not the oil of this plant. Also, Melafix is, if anything, a tonic. It's not something that can replace antibiotics. In a clean, balanced, healthy aquarium, fish that have injured themselves will heal with no problems. Melafix seems more to be geared towards situations where the conditions are not ideal. I've tried it experimentally and the only change I've noticed is that live plants benefit from it and female apistos turn very yellow.
