Yellow Tang with red lines

[Reefmx]

My yellow Tang has some red lines in his body. Any ideas?

Thanks

Sounds like a bacterial infection. @Humblefish ?

Ooh, not good. I'd guess bacterial infection just by the two photos. Try hopping on the fish disease forum. https://www.reef2reef.com/forums/fish-disease-treatment-and-diagnosis.771/
There are tons of good articles and information there.

Septicemia potentially. Ask in the fish disease forum rather than the lighting forum.
