I am sorry no one is replying.Probably because no one as any idea, including myself. Maybe you could go to a different forum that deals with frogs and toads. I am sure there is one out there! There are forums for everything. I hope you find that there is nothing wrong with your little toad. Good luck.
It isn't as active as some are, but when my whites tree frog had a skin problem they were able to help me and even directed me to a vet who could help out.
