Are you able to remove that bump? Is it soft? or Hard? What have you been feeding it? What do you think have caused this issue? Is it a newly acquired animal to your collection? What is the temperature you are keeping it?
Can't remove it, haven't really attempted it either though. I've poked and prodded at it a couple of times, trying to figure out what it could be. She shows no discomfort or aggressiveness towards me when doing so.
I purchased them both a few months back and they seemed fine until now. The one I assume is male is doing great. The other seems to be skinnier, spends more time on land or hidden away. I'm new to Amphibians so these are my first. I've rescued snakes and reptiles in the past so my main experience is with those.
Before purchasing these guys, I did most research of Cynops Orientalis and was intending on purchasing a pair for me and the mrs. When I bought them, I was told they were Paddletails. Up until finding Caudata.org, I believed I had Pachytritons. I set up a tank to fit the needs of Orientalis originally, then adapted it for Paddletails only to find out I have Chinensis. From what I've read, they require highly aquatic set-ups which is fine, because that's what I have. A 45 Gallon tank with plenty of hides and water for both. Current is also taken care of.
I've heard of them being aggressive during feeding, so I seperate them and feed them outside of the main tank. Usually in a tupperware to avoid contamination of the water.
Right now, the sick "female" is in a quarantine tank. No filter, cooler water and regular water changes. She's been in there for a few days and seems to be fine. Her eating habits seem less motivated but her mobility is fine. It doesn't seem to affect her swimming, although when I awake, she is usually out of the water on a rock. I always worry and assume worst case scenario until I remove the lid and stir up the water with a turkey baster. She wakes up and dives back in for underwater acrobatics. Chasing my finger back and forth.
I'm unsure of salt baths, and I don't want to resort to something if it's not the cure.
I don't know what to do!
