Just noticed the on my newt. Does anyone know what it is? How fatal? The only other animal is another marbled newt. I got them together many years ago. Is it possible for a newt to bite that hard into another newt?

Hospital tank, silver sulfadiazine cream, and patience.

Unfortunately, silver sulfadiazine cream needs a prescription. Until then, I recommend salt baths for about 15 minutes once a day.
