Need Help on ocellaris clownfish Tail problem

[naynesh]

Hi

I noticed over the few days the tails of my clown fish started developing some kind of white marks on its tail. it started on 1 fish then the other one got it as well.

I'm not sure what it is and have been researching but couldn't find anything close to what I can see.

Water parameters are reading fine
Water changes once a week
Tank is about 3 months' old

I put the fish in about 3 weeks ago

Attached are the photos.

Any help appreciated
