Good Idea Wally,
here is the link

It is now available for my distributors to order, so it should be available in the next week or two.
I feed this freely to a breeding group of five or six geckos and they eat it up just fine... if one eats more than another, it is no big deal. The safe range of the drug is such that I made it so there is no way a gecko could eat enough of the food to get a toxic dose.
It might not taste as good, but they seem to eat it anyway... You can skip a feeding or two before you offer it to insure their appetite.... Also, geckos infected with Entamoeba are essentially starving to death because the bugs line the intestinal wall and prevent nutrient absorption.. so they actually are quite hungry and eat a lot when they are actually sick from it.....
Please note I have Syringe feeding protocol in the updated instructions that can be used to make sure they get the medicine if you have the time to dose all your geckos individually.
