Not sure what my clown has

[djlc13]

I recently noticed my clown had white coloration on his top fin and rear fin. The clown is perfectly fine and is very active. Not sure what it could be, it doesn’t seem like ich. Tank is 10 gallons and lives by herself because she is aggressive.
PH- 8.2
Ammonia- practically by 0
Low nitrates and nitrites
