Strange case regarding S.i.infraimmaculata

[Niels D]

In the spring I moved my animals from paper towels to forest dirt. They were doing very well as you can see on the vid (repost):
Feeding S.i.infraimmaculata - YouTube
After a while one died and another animal started to show strange behaviour. His movements were abnormal and he walked in a strange manner. First I thought it was a chlamydiaceae disease, but his appetite remained. Check this interesting article:Novel Chlamydiaceae Disease in Captive Salamanders - - Emerging Infectious Disease journal - CDC A lack of calcium was possible though I allready gave it a lot.
Watch him walk:

He also couldn't flip himself after I put it on it's backside. This is always a bad sighn. He got bloated shortly after the vid.
I thought all hope was gone, but since he's moved back to paper towels he's doing a lot better. His movements are almost normal again. He kept on eating and growing. Still his appetite has grown since he moved. Alas he's still bloated, but since he's eating and acting normal I'm not that worried. Hopefully this will go away now temps are dropping. This is him now:

Forgot to mention that the others are doing fine. I'm keeping them all seperated.

My first thought was also a calcium deficiency as it´s well known that these require more expossure, but if you are offering it in abundance that would seem not to be the problem, unless they require more than what you are actually providing or the source or methodolody are ineffective.
I´m not that familiar with the bacterial infections but i´ve heard of them and they seem to be very widespread. I hope we learn much more about them and how to prevent/treat them.
I wish i could be of any help :S Good luck!

Could be flagellates, so I've been told on facebook. Will be checking it's feces asap.

This is one of the healthy guys:

Luckily the bloated animal is doing better. He kept on eating like a pig, so what caused the bloat will remain unknown. Feces was okay, so that wasn't the problem.
