Strange disease on a kaiseri (swelling on the spine) : help ! [With pictures]

[WilliamBlake]

Hello,

I post here for a friend of mine who has a problem on a young adult CB N. Kaiseri.

It has a kind of swelling on the back about the size of a pea.

- It has appeared suddenly and within a week (that is to say it wasn't there a week before).
- The size of this bump hasn't changed since it has apeared about 10 days ago.
- There is no trace of any wound, the skin is perfectly normal on this area
- The animal remains normally active and feeds well for the moment, it stays in the water

Here are some pictures I took for him, we would really appreciate if anyone had any idea to help cause we both do not know what to think of it...

Sorry, I cannot see the photos. Starting suddenly, it sounds like a blister of some kind. Probably best not to wait and see, unless you can get veterinary care.
