I recently purchased 3 chinese fire bellied newts. Larry, Curly, Moe . For the first couple weeks they got along. However Moe the largest started picking on Curly the smallest to the point that I separated them. Since that time Curly hasn't been doing very well. He doesn't eat or move around nearly as much . He has two sores now on his back and a fat lip. The sores look like holes in his skin revealing white flesh beneath. The local pet stores have been unhelpful thus far. Is there's any kind of medication or treatment for this? I've read online that saltwater and or colder temperatures. But how salty and what temperature hasn't been posted. Also Curly still lives with Larry. Should I quarantine them from each other ?.Any advice would be greatly appreciated.
