It is on the bottom behind the head
 
Could be an infection, the white if it looks like a cotton ball would be an infection. I’d probably remove and treat with kanaplex if it were my fish. @vetteguy53081 what’s your thoughts?

Need clearer pics as these are fuzzy, but can be overfeeding. egg-bound or constipation

Tough to see clearly.

How long has it had this?
Any changes in the fish’s behavior?

It looks like it could be a ruptured abscess…

It is acting normal has been around 2 or 3 days
 
Atleast that I know of

I’d say this is a ruptured abscess. As long as it doesn’t turn redder or get larger, I’d just watch it for now.

Treatment, if needed, would be a broad spectrum, gram negative antibiotic dosed in a hospital tank.
