There are only some small plecos around that she couldt eat. But i think i still have them all. I dint notice annything on her 3 days ago!
 
Cant really see a tumor coming on like that in just 3 days.

Agreed too fast for what you would normaly expect from a tumor. An absess could appear that quickly however so it could be a localized infection. Similar to a boil type infection.
 
He said he didn't notice it 3 days ago so it could have gotten bigger to the point it was noticeable but you are right Nero, absess seems more likely.
 
is it a big air pocket???? I had a small marble break her back one time. but you could see it in her tail as well.
