The Oscar in question never had a nostril on its left side. Noticed it a few months back but didn' seem to be an issue. Maybe it' something to do with that. She is acting normal otherwise.

No other fish are showing any issues.

The cons have 1/3 of the tank, all others in the other 2/3s of tank via a divider.

My baby oscar has this and I can't find anywhere on the internet any information about it. Did you find out what it's from? Is he still alive?

If you look closer, Toni only has one nostril. Apparently she was this way since day one of me getting her and I never noticed it. I assume it was some kind of nasal infection, it went away after a week or so and never came back.

As seen here, she has no nostril on her left side.

Wow you must've panicked when you found out she had one nostril. She's gorgeous by the way.. I've noticed today the lump has gone down abit.
One question was you cycling the tank at the same time it happened? I'm almost done with my cycle I dose with prime and stability.

No at that point the tank has been running for six months or so. When I got her she was just barely an inch long.
