There are a few options available, that's just what I've used. You can use some Acidophiliz+ or some dairy free soy yogurt as well. http://www.beautifuldragons.com/Acid.html You can check the bird section of your local reptile/pet store and see if the Bene-Bac is there. I couldn't find it at Petco so I ordered some on Amazon. Just be sure to pick up the bird/reptile version. What I have came in a big syringe that was marked by dose. I gave a dose (1 notch) every couple three days during and for a few weeks after treatment.
