Why is your fire belly toad swollen?

A swollen fire-belly toad may indicate several health issues, including an improper diet, stress, or an underlying illness such as an infection or parasites. Swelling can also result from water retention due to poor habitat conditions, like inadequate temperature or humidity levels. It's essential to assess the toad's environment and diet, and if swelling persists, consult a veterinarian experienced with amphibians.
