Help! Lesions on purple tang

[bw3002]

Purple tang developed these lesions two days ago, only fish are the tang, 2 clowns, file, diamond goby. Could he have been tagged by an anemone or is this something worse?

Fight marks?
Scrapes from chase?
Looks fast and new.
Any damage on fins?
Clown might try that….

Couple chunks from fins. She's usually an aggressor so the clowns standing up for themselves wouldn't surprise me

Head and lateral line erosion. It also effects the fins and tail...which is doing to your fish.

Need super water quality and a variety in the diet.

I would also say HLLE but it doesnt happen overnight. Do you run carbon? Do you feed a varied diet mostly consisting of algaes? Hows the nitrate and phosphate level in the tank.

In 2 days?

I agree. But I think the timeline is incorrect. I could be wrong. @bw3002 what else is in the tank?

I’ve seen HLLE develop fairly quickly. It is also pretty common for folks to miss the initial signs of it.

There isn’t anything else that causes these symmetrical erosion on the head, and the notched fins are also a symptom of this in zebrasoma tangs.
