What’s on my Foxface?

[ElementReefer]

~8mm white lesion with ragged edges
Onset: In the last couple days
Location: Right side dorsal aspect
Behavior: Normal
Tankmates: Cardinals, clownfish, blenny, firefish.
Recent changes to diet or environment: Started using an IM food defroster 3 days ago, so their food comes out slower and they are more competitive for it

I see what appears to be an injury or even bite from another tankmate and with the circular shape has become a bacterial issue. Best recourse is to place fish in a sterile quarantine tank and treat with either Seachem kanaplex or maracyn 2.
If this cannot be accomplished, you can utilize Ruby Rally Pro within tank But it will take longer to both treat and address the issue effectively. If QT, add aeration adding air stone and maintain Good water quality

I went with the minor infected injury hypothesis. Soaked some nori in Focus and doxycycline and gave it to him x3 days. He’s doing fine!
