A full dose of melafix is NOT good for BGK...I know this from experience.CFC said:I would advise adding melafix to the tank and doing daily water changes to keep things clean, melafix is a 100% natural remedy with the only active ingredient being 1% tea tree oil so will not harm any of your fish.
NEVER treat a tank with a strong medication like those intended for internal bacteria unless the situation really calls for it as these medications will kill off some of the bacteria in your filters and cause problems with water quallity and oxygen levels.
If a person does the full dose for 3 days,I have no aoubt the bgk will die.
Scale-less fish react much dif to it then scaled fish.
Could you provide a list of medications intended for internal bacteria that would kill off the beneficial bacteria in the tank? I know of very few that have that result and none of those would be appropriate in this situation.
