Possible Shell Rot?

[slugthebug]

Hey there,
So recently I received an about 7 year old male Russian tort from a home that couldn't take care of him anymore. He used to live with one other male in the same tank. I noticed that little chips in his shell were missing with white spots underneath, and after further research I'm worried it might be shell rot. I don't know all the details about his previous home but I don't believe he was soaked on a regular basis if at all. It might just be wear and tear from living with another tortoise, but I'm really unsure. I'll put some pictures below, thanks!

It's just battle damage.
Very common to see on a tough Russian.
There is no reason for concern

Russians don't get shell rot, and the tortoise species that do get shell rot get it on the plastron from being kept too wet all the time.

Looks like he has been in a lot of battles.
