The company will tell you what you want to hear- yes, the medication is safe for most fish, but bettas are not included. It was made to sucker people in to get more money for the company, but at the risk of the health of the fish.
Many people have reported firsthand the sudden deaths of their bettas after using this product.
Labyrinth fish, like bettas and gouramis, can be seriously injured or even killed by the use of BettaFix or MelaFix, the stronger formula. While other fish can tolerate melaleuca extract (the active ingredient in Betta/MelaFix) quite well, the labyrinth organ present in bettas is highly sensitive to it. The melaleuca can burn the labyrinth organ and at high enough concentrations or with enough exposure, can damage the labyrinth organ to the point that the fish cannot breathe with it. These fish cannot breathe using their gills alone and will suffocate as a result of this.
Also, note that melaleuca is a harsh antiseptic and an irritant, speeding the healing of torn fins and tissue by irritating the injury site to speed up healing. This would be similar to putting alcohol on a wound.
Unfortunately, it is an irritant that seems to have an adverse effect on certain fish. Most fish can handle melaleuca just fine, this includes most "scaleless" fishes as well. So far, the fish that seem to have problems with melaleuca are anabantoids and pencilfish. Since it is an irritant, it is not unlike using alcohol or peroxide on a cut or a scrape. The melaleuca irritates the cells to speed the healing process. With most fish this would be fine and it wouldn't harm the fish in any way, but labyrinth breathers are different. Their labyrinth organs are sensitive to the melaleuca and with a full dose of Melafix, you can kill a betta or a gourami within a few days. The labyrinth organ is the most important organ in a betta's body, that is it's lung. Like humans, if an irritative chemical gets into our lungs, we will have adverse problems from it, possibly even death, the same goes for bettas with a dose of straight Melafix.
Yes, the ingredients are watered down in Bettafix- but since it requires you to put in a whole dose every day for 7 days before a water change, you are actually putting in quite a bit of it in there.. and it has been known to kill MANY bettas within days of use.. not just one or two.
