I looked up aureomycine, it appears to be a tetracycline derivative, the first tetracycline discovered, but after googling "aureomyacin frogs" I didn't find any references to it's use on frogs, apart from some old studies about the development of tadpoles. I don't know if it would be safe for them or not. I have used another tetracycline, API's T.C. Tetracycline on frogs before. That stuff can be a bit rough on the frog from what I've seen. Is the aureomycine in cream, powder or another form?
