my albino oscar has a growth on it's nose, looks like a tumor, is growing, reddish.
eating well, active, but concerned.
water changes and gravel cleaning on regular basis.
how do I treat this, there are 4 other parrot's in the 55 gallon tank.
what do you recommend?

First off Hi there and Welcome...

Can you please post your EXACT water readings for Ammonia, Nitrite, Nitrate and PH... This will help us figure out what might be the cause of your babies injury...

Is a pic or video possible???

The one thing I can tell you for sure is that you need a bigger tank. And Oscar requires 55 gallons to it's self.

But if you can get me that info we can sure work to fix your baby!
