Tangs with scratches

[Shoki]

Hey ya’ll! This is my 265 gallon aquarium. Has been running for a year now.

8” Sailfin
8” One Spot Fox
7” Yellow Tang
7” Majestic Angel
7-8” marine betta
5-6” Blue hippo


All these fish have scratches on their faces. Could this be caused by fighting or rock scraping? Recently moved them all from a much smaller tank that had a lot of rock work..

Looks like it could be the beginnings of HLLE.

How are your water parameters? What is their diet? Do you run carbon, and if so, how much?

Can’t see much.

A scrape here and there certainly happens.
You did move them bigger, but still new environment. They may be having some new territory disputes.
