In another thread, way down, I asked if anyone has had their collection wiped out by bring wc frogs into it, or personally knows of someone this has happened to. I've heard this as a vague fear for years - heard that its happened, but it never first hand knowledge. Its always I heard this from someone else. That's a good way to pass knowledge, but in this case I think it might be passing on fiction. I'd really like to talk from someone this has happened to and to try and figure out why. Better husbandry through knowledge and experience.
