Betta Fish: I’m back again 🙃

I (coincidentally) posted just yesterday about how my betta has gotten much bigger (and darker) since getting her (him?) about 2 months back and seems to be doing well.

Well almost immediately after, this happened 🤦‍♀️
I noticed that (s)he’s now missing some dark scales on her back (additional photo in comments) Still acting normally and eating, but is there anything I need to do as far as helping her heal goes?

(please don’t come at me for setting up a camera before i helped, i was on facetime, i just set my phone down!)
