I know this is an old thread but I found it as I was looking for new fish to pair with my 6 swordtails. I did have some mollies so there is 1 tablespoon of aquarium salt per 5 gallons. It's a 20 gallon so that's 4 tablespoons of aquarium salt.
I guess that would be very bad for zebra danios? If so and I wanted that breed, how long till (weekly 50% water changes) salt is no longer an issue for them?
