Hello, I was wondering if anyone can help me figure out the sickness a fire belly newt had at a pet store. It was missing its arm and it had white at the end. It was not like cotton, so it is not fungus right? Also, their was a white string at the end of the arm (that was missing). Is this sickness easily cureable with a low death rate? Is there a way to know if it is too late to save him? I'm wanting another fire belly, and I would love to get this one, but I do not want to get him\her and it dies. Also, what medications (if healable) do I use? Thanks!
