Large white circle on side of Red Belly Piranha

[MikeyBizzle]

I have 5 rbp in a 125g fish tank...
And my one has a large circle on the side
Of it and I'm not sure what it is any ideas?
None of the others have it just one...

They are wild caught and I've had them for
About 10 months and they were 2" now 6"

could be bite marks.piranha's tend to bite chunks off one another when hungry.pic would help

It was just bite marks... Weird though that it just started about a year into their lives...
