Poison dart frog hobbyists tend to use the most natural products available. I'm not sure if the same goes for other types of frogs. I would be concerned about the makeup of the 'butter' content.

If it was me, I'd start over and make a new batch of culture, but I raise poison dart frogs. I'm not sure how hardy your species is. What you have may be just fine - or not.

Just a thought -
