My firebelly newts toe/foot/leg is gone! What happened and what should I do?
There are two possibilities. A tankmate could have bitten off the leg. In this case, remove the offending tankmate. More commonly, a limb can be eroded away due to infection. This is common in newly-acquired wild-caught newts, particularly Chinese firebellies. Keep the newt cool and clean. If the newt is strong enough, the leg will grow back. If there are signs of infection, see Treatment of Infected Wounds in Newts or Caudate Illnesses and Treatments.
