Salt in general has so little uses in a freshwater aquarium. The concentration that's fish safe is virtually usless. For a few things it can be used as a dip, that's what we did 20 years ago. Lol. With labyrinth fish and scaleless fish you have to be extra careful with not only salt but meds in general.[/
Since I don’t know much about bettas can you tell me what you think of his fins? I normally do 50% water change every week, so do you think if I do 2 water changes a week it will get better?
