Is it just some sort of external damage? Or is it something that is actually growing, like a tumor/cyst or something?

my p had a little nick like that on his chin..but it is going away...probably bumped his face

Happens when they spook and hit stuff at fast speeds... Nothing you can really do to stop it. It just comes and goes.

It did look like a physical injury. It will heal with good water quality. But, since the OP said "stop this," it made me wonder if it was something that was growing, i.e., he/she had watched it, and it kept getting bigger. I'm just not sure.

no lol i c alot of piranhas that have it and i was jw how to stop mine from getting it lol

I think its a blister of some kind from the fish's chin bumping and rubbing the glass. Half of my piranhas get that little bump once in a while and then it goes away after a week or 2...and sometimes repeats.

Yeah it's called a chimple and is caused from fish rubbing up against the glass.. Tank size usually causes a chimple to appear when it not big enough for the fish. Melafix has always gotten rid of chimples from fish that I have bought with chimples

Looks like the beginnings of a callus to me...........very common for P's to get callus from banging into things ..........the spook easily...........it might go away it might not but it's nothing to get excited about just a part of raising P's in glass.

what they said but sometimes it has nothing to do with tank size (I had a 6" rhom in a 180g before it still rubs on the glass and had a small chimple), if the fish likes to rub on the glass there's nothing you can do. put some plants and stuff to reduce the chance of it rubbing the glass.
